Completely agree with the above.  Play with them a few rounds to see how well you hit them.
If you have access to a launch monitor (GC3, Trackman, Uneekor/AboutGolf or an indoor driving range where you can hit real golf balls), go hit a bunch of the shots and compare your carry distance and launch trajectory to see how you like the clubs.  I think at PGA Superstore, you can rent indoor hitting bays.  I think it will be money well-spent for you to get a more accurate gapping and carry distance of the clubs.
I bought a GC3 when they were released in 2021 and recorded all the average carry distance (on good hits) of my whole bag.  I found playing the carry distances of the clubs helped improving the GIR and scores.

I have the Spornia 8 foot net and it’s great.  It is expensive, but the well worth the money in my humble opinion.

I have had a lot of expertence with used golf balls.  I rarely buy new balls anymore, unless there is an exceptional deal. Whether the few roadblocks are surmountable is up to you.  The 5A balls mean pristine (usually), no marks, no water balls, played less that a round, etc.  The cost of those is not far of the new cost.  It also depends on whether you insist upon tour-type balls- Pro Vs, TP 5s, etc.  Cost for those is considerably higher.  I usually buy 4A balls that will have player marks and logos, neither of which I care about.  The problem with below 5A ratings is they become subjective, so you have to be careful of the quality.  I have had greatest success with Jerry's Goll Balls on eBay.  (No, I am not Jerry, I don't know Jerry, I am not being paid by Jerry, etc.).  He normally displays the golf balls in a 3-D pyramid (like on some ranges.)  I have bever had a bad batch from him and the prices are lower than many.  What I do in shopping for them on eBay is figure the price per ball and compare the ones I like.  Look out for exorbitent shipping costs, especially when buying in bulk.  Price of shipping everything has gone up.  Usually, the good sellers on eBay will have multiple photos of the balls you are buying.  There ared good and bad sellers on eBay, like anywhere.  Give it a try.

The only golf ball resale site I know of where their business model of repackaging original best quality balls is Two Guys With Balls at https://twoguyswithballs.com/   They have a partnership with The Stick & Hack Club at http://stickandhack.com/ another high degree of integrity organization that has earned my ongoing support by being focused on providing best value.  
Edit:  The balls for the first Stick & Hack Club Challenge weekend in May 2022 at French Lick Resort, Indiana were courtesy of TwoGuysWithBalls.com and they played well.

One characteristic of a really good instructor is the ability to explain a concept in a variety of different ways.  Our brains all work differently, so a feel or image that works for me may not work for you.  Luckily for you, you ran into a guy who used an image that works for you.  Congratulations!  If he teaches in addition to fitting for Edel, you might consider seeing him for lessons if the need arises.

I chuckled reading this.  This was very reminiscent of my experience with the Grafalloy Blue 65S.  This when I first started trying out non-stock driver shafts.  For the longest time, I could not hit the ball higher than 3 stories high.  That shaft always felt quite boardy and frankly I never had enough clubhead speed to play that badboy.

I'm going to go out on a limb and say for the sake of financial discipline that luxury golf launch monitors are in the realm of things that shouldn't be financed. I could see financing being a viable option if this is a business that is returning earnings from the use of the item but from a personal finance perspective, this seems like a questionable decision assuming the LM is a depreciating asset.
For anyone reading this, please do yourself a long-term financial favor and be careful if you're looking at things from the perspective of monthly payments. If you don't need something and can't afford to buy it outright, you should really carefully consider your purchase decision before you finance the purchase. If you finance the $7k GC3 at say 5.5% (optimistic), you will have a monthly payment of $211/month over three years or $134/month over five years. The total cost of ownership over three years would be $7,596 and over five years, $8,040. That's $600 - $1000 of interest that you will never get back. If you don't have a flawless financial picture and the interest rate is 8.5%, then the three year monthly payment would be $221/month ($7,955 total) or for five years $144/month ($8,616 total). That's a lot of money going down the drain and for the love of God, please don't finance this on a credit card with rates that range from 16% to 29%. We haven't even included any sales tax that would likely bump that number up another $400 - $700 depending on your area.
Sorry for the rant, I just see too many people make poor financial decisions for things that are extra. If you have the cash to burn, then feel free and buy it but if you don't, please think very carefully and don't make a rushed decision. Please keep in mind that the SkyTrak is also a perfectly capable device if all you want to do is keep your swing in somewhat reasonable shape over the winter.
