Steve442:
I'm currently at level 87 and was wondering if I should go for the Burner 2's now or wait for the R11's at level 90?
All I will say is this: There is a long way to go till level 90, and I mean 10's of 10's of thousands of xp's. Unless you are playing 7or 8 tourney's, and I mean 18 holes, a day its going to take you a while.
If you are happy with the irons that you have I would suggest waiting for the R11's, or maybe, as suggested , any new irons that may come out in the meantime.
Your choice but , in the meantime, Happy golfing and have a Happy and Prosperous New Year.
