CRT.5 as my next basher?

Actually, I would run 3s. 2s will require a decent amount of current to get the speed you want. And not only is high current less efficient, the sidewinder might heat up a bit. My full MM ESC heated up quite a bit running the 4600 on 2s, and that was geared 46/12. Needless to say top speed was crappy. I can't imagine the Sidewinder will fare any better heat-wise on 2s. And using normal 2.2" tires is effectively like gearing up a tooth or two, so that just makes things worse.

Yeah, you can gear up the 3300 to compensate, but the required current of a low kv motor geared high will be just as high as a higher kv motor geared down to get the same speed. So you don't really gain anything. 2s can work, but I would definitely go 3s. Believe me, I didn't relish the idea of buying new 3s lipos either, but I'm glad I did. Now, my setup is not nearly as finniky with gearing.

I think you'll be happier overall with 3s. And any comparable 4wd vehicle will benefit from 3s, so this doesn't apply just to the CRT.5.
