Well, there is 2 sides to your problem
One is skill/technique, other is equipment
Imo, the Extreme S is likely faster than TBS
And with all due respect, from your reply, it seems that you also have skill/technique issues.
So if you really do have skill/technique issue - changing equipment is not going to fix the core problem. It may help, but that is just covering up the problem.
Thus, I think it is best to get some coaching advice as well.
If you have funds - change to a slower blade
Or change to softer rubbers - which will allow you more dwell time (Equipment some times does play a role with one's style/technique)
Or if you really have funds - get 3 to 5 coaching sessions, or get some "good level players" to comment free of charge for you and advise you on what is wrong and then fix up any equipment issue
