I currently use the Silver Real Bowlers Tape in the front of the thumb. I tried the Turbo Grip Strip colored tape (orange, I think) but didn't care for it at all. Didn't stick well and wasn't grippy enough. The Real Bowlers Tape gets pretty dirty, though. I don't find it as durable as the older white tapes (before they all got pretty gooey). The Powerhouse White is also pretty good. I might give that another go again soon.
As for the back, I only use Ebonite black. It's thicker and firmer, which makes it MUCH easier to insert and remove than the standard thin black tape. I also find that it leaves no residue, unlike the thin black tapes which almost always leave a lot of stickiness behind for me (and they tear easily, another demerit).
I have used various Hada tapes and thought I had settled on the Vise Blue, but now I find that I like the Motiv Black even better. It sticks to my thumb PERFECT every time and it gives me a great release. I tried the Motiv Grey and Orange but they were a little too slow for me as I like a quick release (too bad, because I like the orange color!). I am going to try the Genesis Red tape next. From what I understand, Genesis makes the Motiv tape so I'll see if the Genesis Red is identical to the Motiv Black (in theory, they should be the same or pretty close).
