Have you ever used a Zowie mouse with Huano switches? I went from a Deathadder 2013(4G) to a Zowie EC2-A .. which is the smaller version of the EC1-A that's already been suggested. The shape of this mouse is more comfortable to me than a deathadder. The clicks are indeed stiffer but not by very much. I can still spam them easily, and the sensor implentation in this mouse is top of the line. Honestly I don't buy into the "special sauce" that FinalMouse is touting with their mouse' 3310 even with it's "custom" firmware. The fact of the matter is Zowie has better build quality, and has the best cables on the market. My awp flicks improved massively when switching over from the DA. Night and day difference. The tracking is excellent, and it's given me much better pistol round results. Getting 1 taps with the USP is almost effortless if my aim is warmed up.
This is the first mouse I've owned prior to my old MX518 that actually feels like it's an extension of my hand rather than a mouse when holding it. It's like the perfect shape for all styles of grip. You can palm it, claw it, finger-tip or any hybrid of the 3 conventional grip styles. It's kind of rare to find that in a shell design. It's the perfect weight to me, not too light that it feels cheap, and not too heavy that it feels like a brick. I believe it's around 85g (the ec2-a version).
Some don't like Zowie because of the side buttons, which are indeed lack luster.. but they work and perform just fine. They do the job. I've never felt like there was any delay to my clicks since Zowie addressed the click latency to put their mice in-line with most other gaming mouse on the market aside from the Logitech mice which still edge it out slightly. The fact is, Zowie mice are designed for the competitive player in mind who want something with excellent tracking, LAN ready, comfortable designs, very low LOD, and no additional bloat from software since it doesn't use any, just like the FM. I also prefer the fact the DPI button is on the bottom, compared to it being on top with the FM.
Good luck with your search. I will be purchasing an FM ambi version which they release it since it's going to be their first "real" mouse they release. IE: Won't be an OEM shell with their sticker on it.. and because of that one would expect the build quality to be MUCH improved. Hopefully.
