By the numbers. Launch readings for suggestions.

Just went to the launch monitor and heres what I got:

R510tp 9.5* Zcomtw64 S flex(freq 248):

Launch- 10.5* spin- 2966rpm ball spd- 148.0mph swingspd - 104.3mph

Generic 10* GD YS 8.1 X flex(freq unknown):

L- 10.8* S-2429 BS-158.7mph SS-106.9mph

L- 10.2* S-2153 BS-160.6mph SS-112.5mph

Generic 10* Speeder 661 S flex(freq unkown):

L- 12.1* S-2232 BS-148.4mph SS-107.0mph

I'm looking at trying the ys8.1 to see what I get out of it in actual play. I have a tendency to get over on the ball, smothering a lot of shots left. I need to stay more centered through the impact zone, working on it. I have no problem swinging from the inside, my path was/is pretty consistent at the 2-3* inside range. I don't fully if at all release my body and club through impact, resulting in a lot of pulls, again I'm working on it. Anybody have any suggestions on shaft options? Any responses to the numbers? Thanks for all your help...
