SFI Roll Bar Padding. Is there any information/specs on the SFI padding versus the high Impact (hard stuff)? SCCA still just recommends, not mandating yet. If they act the same during impact and burn (no drip) the same then I am going to save myself $6 a 3' stick.

I have hit my head on teh soft shtuff and the high impact stuff. I will DEFINITELY use the high impact stuff, a lot less little birdies flying around the head. Just don't know whether I want to spend the money if I don't get any performance advantage. I know, I know, SFI? Performance? What?
