Hang in there Rowdee, your game will come back.
As you have already discovered, you are going to have to relearn the courses. I too loved my Raptures as Pro. But when I made Master, I decided I was just going to have to adjust to higher meter speed clubs and got the G10 Master 3W, hybrid and irons and the R9 driver.
My strategy was to experiment with different balls and play the weekly Unlimited tournament repeatedly. I played it about 30 times a week for the first 4 weeks after I made Master, posting every score. My average did go back up over 70 early on during this period, but I did learn the courses.
Now, two and a half months later, I am still learning better ways to play certain holes, experimenting with different shots in different situations and working very hard on my short game. All that, and I'm still deluding myself with: I'll Be A Great Player If I Can Just Learn To Putt!
Sometimes I miss the slower meter of the old clubs - any ex-smokers here? - but the GI balls help.
