Your driver is fine. Really wanted to up it the L90 one is OK, just not as easy going v the competition - You will be replacing it later.
Your Irons - Good but IMO the key area of concern. Better trajectory exists. especially if that 3 iron comes out it's that now and then difference with the L90 set.
3 wood - A better one might buy you a club down at the last, not really your issue out there, IMO.
Putter: I just swapped the one yo have for a new toy, and may still go back to it. PersonallyI think you have an excellent putter, and can have every confidence in it.
I just shot a 57......My issues working off an old chart I put together for a L90 iron set, and slightly upgraded for the L97 set. Pressure on putting especially at the par 3s is the result, not night and day but chasing down a 54. Got away with it when I was playing all time but a longish break I am rusty without a complete chart of me as a crutch. Others don't need one fine, but IMO best to have one. .............I was disappointed to miss a couple of across face putts too..........My fault, no excuses. I think it's all playing fine, no underhand WGT tricks that I could see, all down to me.
EDIT: restarting at the first should take between 0 (TW off the bat) and 40 seconds MAX. Eagles should happen 30% of the time from there blinfolded - L90 set???
