I was kind of stubborn too.  Didn't take a lesson for a while, tho I had many injuries.  I rejected 3 teachers where I had 1 free lesson, and didn't achieve anything.  Then I had 2 short lesson sessions and signed up and am very happy.  Talk to a professional for 5 minutes to measure for your personality. 

Before moving onto a different club there are things that can be done.
Alignment, grip, setup. Check all the basic stuff.
Then for a very cheap price get a dry erase or sharpie marker and draw a line on 3-4 balls. Make sure the clubface will hit the line. Use this to check to ensure you have the proper lie angle.
If going the different club route I would suggest getting fit so that you save time and money by not having to tinker and get used to the club or constantly having to make the swing work

If you have pretty good ball flight but it is consistently left i would make sure to check the lie angle and see if it is too upright for your swing.

You are not wrong, I should get a lesson and .... (Gasp) I've never been fit.

Maybe I didn’t explain that properly - sorry - we should always be improving but the improvement should come in our swing - the clubs we play should enable that improvement not force us to change the swing to fit the equipment - if that makes sense. 
 
 

Offline could be alignment and not the club or it could be the swing and not the club.
or it could be the club doesn’t fit your swing and is causing and issue with your delivery.
Learn what? 
 
If it’s learn to make the clubs work for me then no. The clubs should be working with me, not me learning something to make them work.
Im also not learning what they do. I learned that in my fitting whether I self fit or had a fitter do it.
If learning means to get better at golf then I am learning but I’m doing it with clubs that again work with me not me working to make them work

With these clubs you simply end  up a dispersion pattern that is a little more left.   Don't know if it is more draw or pull but your path could be a little more toward out to in, face could be more closed at impact, or both.   Generalizing less offset would have a more open face.  I'd say offset isn't the issue but possibly club weighting and just how you hit these particular clubs   When you were getting fit/trying the clubs was the left bias showing up?   You could aim more right if you wanted too adjust the dispersion pattern

Thinking of this do you practice with alignment sticks?
