Have to chime in, because I throw Hammer and Roto.
All of the above, mentioned by previous posters is correct! That little flip at the end, that all the Vibes seem to have, is what makes them not quite right for dryish conditions.
The Mars will definitely be a more controllable piece as the heads get fried and the track gets scorched.
The Razyr is Hammer's best dry lane, controllable piece to date. I love the movement and hit of that ball. Just like NthDitch said, you might want to tune the surface of yours with a white or grey pad, just to smooth it out more.
