I was finally able to play with this new shaft in my driver. I love the feel of this shaft and my tee shots were straighter. The ball seemed to be going a tad longer as well. I did get a bit over confident and flared 2 out right but it was because I tried to hit a bomb. This Jupiter Lite is definitely a keeper!!!

Geez. I can't tell you. I still haven't recieved it yet. It left you'll at the beginning of August and it's almost the end of it. I still don't have it. I kinda lost the spark bout it. Hope it's all the hype that you guys promise. If not I'm returning it.

Shaft has really helped to minimize my dispersion on drives. I also have the Jupiter 3 wood shaft with the same results and I’m waiting for them to put out a line of hybrid shafts.
