I never could play Bethpage back nine, through any tier. I find BP hard now due to the V2 rapture pro irons just aren't long enough to reach some holes adequately and par or worse is my best after four month's of play. The G10's for master is what's needed to play successfully on BP back nine. the 210 yard 3i will reach those long holes, IMO.
The V2 pros have adequate length on Kiawah, but that goes without saying.
Anything is possible in golf, be it on a real golf course or the online variety.
Edit: I proved my theory right. I shot a 64 today on Bethpage. With golf, anything truly is possible.
