Congrats, you are clearly a decent player - so WGT will shaft you.
It's hard at level 74.
I made Master at level 40 and Legend at 72. I
struggled with distance both times - sometimes even if you ding the tee
shot you won't make the fairway (certain holes with a headwind).
There are a few drivers you can get now which would help as well as balls with distance - but ideally if you can wait until level 81 (like I did) and pick up the higher level G20 (280yards) and wood (240 yards) you won't have any problems.
Also that driver you have is Med/High loft which makes trees and obstacle - I hit plenty from the Legend tee with it. As someone else said - using backspin will loft it. You could also consider using a punch shot to keep it low.
The Legend tee is tricky, sometimes the distance increase is small sometimes it's massive.
The 2 holes I have noticed it most is hole 17 St Andrews and Congressional 18 - both are a full 60 yards behind the Master tee which make them a challenging par.
You may also have to play a few Par 3s with a driver.
