Cutting TREX

I am going to be cutting TREX for a stair/decking project and wanted suggestions on the blade I should be using. I have the 40 tooth Diablo on my saw which has served me well but I wanted to see if I would be better off switching to something like a 24 tooth blade (TREX recommends a blade with fewer teeth). I know that the Diablo 40 tooth is considered the best all around blade to use with the EZ system but don’t know if it will work well for cutting TREX. I do have a 24 tooth blade but if the Diablo 40 tooth will work well I would like to stick with it since it won’t require cutting a new anti-chip insert or rail insert.

On a side note, my saw is a Hilti 267-e with variable blade speed, what would Hilti owners suggest as the speed setting for cutting TREX?

In working with that type of decking my instructions recommended 24 teeth on a 10" blade. You want as much space between the teeth as will do the job ( to reduce melting). Even with the recommended blade I had some melting (but I could just snap it off)

When I built my front porch (13-14 years ago) I cut Trex on a 12" miter saw with a 60 tooth blade. I also ripped it on a 10" table saw with a 40 tooth thin kerf blade, and planed it on a Parks-Belsaw 12" planer (don't ask why), it machines well. Haven't used Trex since I started using EZ, but will in a year or two when I build a deck and walkway.
