I have been using the Zowie EC1 evo for a while now and as far as shape goes it is pretty much the best mouse for me and believe me i have tried a lot of different mice. (DA, Xai, mx518, etc)

However the problem is it feels really heavy to me. (97g without the cord)
So im thinking about replacing it for a mouse with less weight....

I've looked at a couple of mice and the FK looks good so far, as it only weighs 85g. What somewhat worries me is switching to a neutral shape after using a mouse designed for right handed players...

Any ideas/suggestions?
