Hi. I've tried a couple of untacky 729 rubbers. Presto Spin 44 deg: Quite fast. Very nice looping rubber, but not very dangerous. Focus III Snipe 42, 44 & 46 deg: This one is really nice. I used the 42 & 44 for my backhand. Not so fast, but good control and sufficent spin. The 46 I tried on forehand. Nice looping rubber with very good control, but I'm used to H3N and Battle II Pro, so the effect wasn't quite like these. And it's quite light, the Presto as well. About 40-44g cut to normal blade. Bloom Speed & Spin in 45 deg. The Speed is a H3N-like rubber, but not as good in all aspects. The Spin felt dead. Didn't use it for more than an hour or so. Focus I is tacky and slow. Tried it in 42 deg. Good control backhand rubber. I had a Battle II 36 deg some years ago. The feeling was good, but no catapult when looping. Battle Pro and Pro Gold feels better than all of the others on forehand. Somewhere like H3N, but better control, and not quite as much catapult. Very nice forehand rubber (for me).
