Is anyone using MDF to makes "trial" carves before breaking out the "good wood"? I was using pine & poplar for the trial runs, but it's so hard to fine a piece that straight & true with no twist.

I've sort of stayed away from MDF just because I hate the dust. Anybody using it? Anybody have a reason I shouldn't use it?

(yes, I have a 2 hp, dual 4", 2-stage dust collection system)
