I tested out multiple drivers for the last few months. I am coming from an r7 SuperQuad so my obvious feeling was to look at TM. What I personally found was the TM felt too light and bit flimsy. I didnt really like it all. After trying several clubs, I actually ended up going with the Nike VR Str8 Fit (8.5*) and just finally tested it out on Saturday and was very happy with the choice. This is coming from a person who loathed Nike clubs up until these past few months.
I had all TM's in my bag (driver, 3 wood, irons) and first picked up the VR driver about a month ago and just yesterday switched to the VR irons. Personally, I think you should give the VR a try (or even that square headed one, but i'm not so much a fan of it...the Machspeed, even though its supposed to go further). I honestly have to say that the adjustability of the VR really gave me a huge boost of confidence. I would give that a shot.
Second my list is the Cobra S2 driver. I only demoed it but it felt really good. Lastly, the new Ping i10 driver is really nice and the only reason I didnt go with that one was because I couldnt adjust the head like the Nike and Cobra. If I could, that would have probably been my club of choice...
