Forget the motor mica crap. The only thing it does is make a mess. I'd also take with a grain of salt ANY manufacturer's claim that their "slick", "super" or otherwise "wonderful" wad/material increases velocity for "free" or other such claims.
I once bought all these bogus claims- higher velocity, better patterns, less fouling, etc. Testing proved it all to be bogus, except, in some cases the fouling part. In response to Spolar's claim that their "special" slick orange plastic was so slippery you would get an extra 50fps from your existing load just by changing wads:
I tested their claim by loading my standard handicap shell with Fig-8, The orange Spolar Windjammer wad, the authentic Windjammer wad and the DRM Windjammer clone. Guess what? 10-shot chrono strings proved they were almost identical. All had excellent SDs, and the average velocity spread between wads was a WHOPPING 9fps. The Fig-8 was the fastest, and the Spolar was the SLOWEST. Not only did I not get the promised 50fps, I actually LOST 9fps.
Claybuster wads give the most plastic fouling, by a really, really great margin. I simply will not use them, even for free. Everything else I use seems to be about the same, fouling-wise.
