Have posted this on the older thread, but consider:
It's a little harsh if you're caught in the middle, but lots and lots
of Masters have played wonderfully with the Pro clubs! (Especially the
Raptures.) Some holes you will have to play now for par instead of
birdie, but let me tell you: reaching the same greens in regulation with
Master clubs is no picnic either. (I'm not even considering the faster
swing speed.)
Look at specifics:
Bethpage - the 7th is easily reachable by Pros using Pro clubs, but
from the Master tees with Master clubs - no. So you're in the same boat.
At least one par-5 at Bethpage (13) is routinely reachable in 2 from
the Pro tees with Pro woods - but almost never from the Master tees with
Master woods.
St. A's hardly matters because the wind and the roll are more decisive than length off the tee.
Kiawah - yes, a couple of par-5s reachable with Master clubs cannot be reached with Pro clubs.
Oakmont: all par-5s are 3-shot holes, and the 9th really plays as a par 5 anyway.
PS. Seekerb, it looks like you're already playing Master clubs, that's as long as they get.
