Hopefully this review will help anybody who's on the fence about getting one of these things.
I bought the SuperSpeed training system back in December 2021 and used them religiously until March 2022.
Here's a quick summary on my progress:
driver pre workout: started at 100, ended at 105
green stick: started at 115, ended at 121
blue stick: started at 106, ended at 112
red stick: started at 98, ended at 106
driver post workout: started at 107, ended at 111.
Just by looking at the start and end speeds, these speeds were amazing. I started with a driver swing speed of 100 mph and got up all the way to 111 mph (no ball). It was such a fast and furious gain, especially since my goal was to get to 112 by the end of 2022. Unfortunately, none of this translated to the course, while I was swinging at 107 mph every single shot had a 30-40 yard slice, and I was have always been a draw player. I've been playing golf for over 20 years, started since little, and have always, always played a right to left ball. One way misses were my bread and butter, and after the training, I had every which way misses. Upon filming myself, I realized that my swing had evolved into a much more hideous form. It was so bad that it was unrecognizable. Basically, I had developed this ridiculous habit where I was flipping my club at the ball. I've always flipped at the golf ball, but this was ten times worse. Exasperated, I stopped the training altogether and looked to gain back form. It took me probably a month (I work a full time job and have a kid, and hence the long time) before I regained form.
So here's what I'll say about speed training, I think it works with these two HUGE caveats:
1. You have very sound swing fundamentals and you employ the same swing during these speed training sessions.
I know the SuperSpeed training people state that you should go all out and not care about swing mechanics and just try to up the mphs. IMO, I think this will ingrain bad habits into your swing. I think that each session should be employed with the same exact swing that you use on the course, except of course at a faster speed.
2. You have time and don't mind re-finding and re-tooling your swing
It's inevitable that after speed training that you won't find the face, even the pros go thru this
It's very important to hit balls after a workout, the ideal situation would be to take the sticks to the range to do the training and hit balls post workout. I never hit balls during my Dec 2022 - Mar 2022 speed training. I had no idea how much my ball flight had evolved. By then it was too late and it took me too long to get back my desired ball flight.
If I could do it again, I would not buy the speed sticks because I just don't have the time. I do believe in speed training, but my definition of speed training is a much simpler one, just go full out on every single drive in the range. Maybe one of these days, I'll try the Bryson speed training system, where all he does is hit drives at various speeds. That being said, while I do go full out on every swing, I make sure that that flight is the correct one, if I see that I'm banana slicing it, I dial it back, and then rinse and repeat. Even with my four month hiatus from the speed sticks, I noticed that I'm steadily regaining my club head speed. I used to be at 107 mph while hitting the golf ball, I'm back at 106 mph.
I hope this helps someone.
Cheers.
