Greetings
When I first saw the R15 I was hesitant after seeing the meter speed. True my L89 SLDR has more forgiveness and slower meter but I was ready for change.
I am not disappointed one bit. I've turned two friends & and unknown onto it and let's just say they are quite pleased. There have been games I kept up or plain outdrove the L98 R1 & L96 Bertha.
Therefore, it is my opinion to say, "why wait". The club is all that and more. By the time you reach L98, perhaps there will be an even better R1. It's my feeling there will be, since this L90 R15 is just as good.
I use the L90 Nike Platinum when I can , more so with the Nike L71, and sometimes L35 Calloway. So a good ball with slower meter should solve your problem.
Good luck with whatever you decide to do. I love it :-)
