What is the smoothest ESC for offroad?

[RogerM]

I'm hoping that 2010 will be a much more RC packed year than 2009 and with that in mind I've been looking at my equipment trying to work out what to change for the better.

Currently I have a Sphere TC in the 4wd and a Nosram Matrix 07 in the 2wd.

I am not overly happy with the smoothness of either, even on the lowest settings they don't seem anywhere near as progresive as my old Nosram brushed speedos.

I am looking at backing down a couple of winds on the motors too (5.5 in 4wd, 6.5 in 2wd going to 7.5 / 8.5 respectively as that I think better equates to the 12/14 turn brushed motors I used to run).

What I would like to know is what speedos people are impressed by in terms of smoothness, especially from those people who have run several different brushless ESCs.

If anybody has any constructive comment regarding motor selection I'd like to hear those too.

What I am most interested in is smoothness and progresiveness as I am still very much struggling to adapt to the brushless set-ups I have.
