HS21 must be different now. It lays like glass pretty effortlessly but man..a week later it's hard as a rock.
Not so for the 3.8. I'd put it up against anyone else's single stage. I've used my fair share of it.. just did 2 allovers with it last year. Never used the 200, but was told the same from my rep..just a cheaper version...price and quality.
If they changed the forumla for the hs21...man they sure did screw up if it was anything like your universal, barry.
