Is one timber more stable than others?
For some time building another cross cut sled and extending the fence behind my mitre saw have been on the drawing board and I am wondering what timber would be the best to use for the fences, are there any particular timbers that are less prone to twisting, warping, etc?
The last crosscut sled I built used pine and within a couple of weeks only two opposing corners were sitting on the table
Cheers,
Howdya

Actually, a lot of the cross-cut sleds I've seen use MDF for the fences (or high-grade ply), just for those reasons--flat, no movement. You might want to consider that alternative.
Cheers,

Bob's dead right. Mdf or ply or even chipboard are the way to go.
After its made and tested, paint it all over with polyurethane which will minimise moisture uptake and give a better surface for sliding.
Some people fit a laminate bottom for wearability and slipperiness but the polyu works well.
