I had an R1. Got rid of it.My swing speed was 94 to 97mph, had the stiff shaft. It felt like a rubber band.
I do have a couple questions....Were you hitting them more left or right and with which shaft? In your Ping's what shaft did you have?
Why does TM have to come out with something different every six months? Now they have the SLDR that I will never try.
The technology can not possibly be changing that much or we would be hitting 600 yard drives by now.
I found a brand new still in the wrapper Ping K15 with a 149D stiff shaft and that so called technology is 4+ years old now and I can not find a driver that will out do it on the market today.
When it comes to clubs (any of them) find a club head that looks good to you and go with that. Then move on to finding the shaft that is best for you. It might be a $50 shaft or it may be a $300 shaft, either way find the right one for YOU. Then find a grip you really like and works best for your size hand and how you like for it to feel. And last but not least (and I'm getting off the subject here) find a golf ball, even if it's a cheap one and stay with that from now on. If you do these things and stop trying to impress your buddies (and I'm not saying you are, but some do) I promise you will play better golf.
One more thing, these shafts that come in these"stock" driver's are "made for" shafts. You may find that a stock shaft is to your liking, mine was in the case of my K15, but don't let all this shaft stuff go to your head when looking for any club. It don't matter what it is, just make sure the club head looks good to you at address and it feels good when you make contact.
