Hm... an ergonomic mouse might suit you better, the Xlite is ergonomic. If you prefer something larger, I'd check out the Deathadder V4 Pro, that's another top contender. Teevolution also makes the excellent Terra Pro, it's an ergonomic mouse that's cloned from Logitech's famed G703, it has an indentation for your thumb on the lefthand side of the mouse it's rather interesting.

All 3 of those (including your Xlite V4) are very high quality, I would honestly look at Xlite ES or Xlite CrazyLight though if you're going to commit to that shape, those two would be really nice.
