I've been fitted, put on the machine who knows how many times. SS is usually somewhere 90-95. I think the longer length gives me an increase in ss.
I'm surprised you have a tj-46 noir 6.2 and can't get the ball in the air. Let me guess, maybe a low duck hook? I don't know, that was my bad miss when I try to over-swing even with the tj-46 noir 6.2 which I had in a different head. I didn't have a problem getting the ball in the air with that shaft. Just from feel, I think the profile of the 2 shafts are slightly different. Tario told me the RD has a stiffer butt section and that feels about right. Both shafts can feel whippy at that flex and really requires a smooth tempo. It feels whippy when I'm taking a practice swing but doesn't feel whippy when I take a real swing. For that flex, I have to think about tempo alot. So the only thing I can think of is that if you have an aggressive transition or some swing mechanics, it won't work as well. I think others have talked about experimenting and finding the right crazy shaft which if found is rather blissful or otherwise frustrating. For a really good all around shaft, even for avg ss like mine, the quadra is a safe choice. For me, this RD shaft is really making me feel I can tackle those long par 4s.
