Welcome to the mens Tee!
It is challenging and it will probably take you a while to get to grips with it - that's normal. You will sometimes notice little difference but St A 17 and Cong 18 you defintely will - they become very challenging pars.
I could be wrong but I believe the biggest way back is Kiawah #13 - a whopping 102yards behind the Master Tee.
In the past hitting Legend before 81 was a real pain (I made it at level 71) but with the new low level drivers with distance it's not such a problem.
I haven't checked your clubs - but the bladez are an excellent choice as there is a LOT of experience (maybe more than double?) between 79 and 90 (for R11s which are the best).
Driver and Wood you gonna need 275yrd and 230yrd minimum.
I would probably say the Cally Xhot 278yrd driver and G20 240yrd wood is a good combo.
The Cally is just a touch shorter than the G20 but it more than makes up for it because it's so forgiving - when I rented it I prefered it to my G20 280yrd driver and best of all, you can buy it now.
You will need lvl 81 for the G20 wood.
