    I used to run hydromotive on my SST. And a 20XD. I liked them.

    I have a Croxton worked 29" X-OB but have never run in on my 21XDC/300XS. Mark told me it was a little stiff and would be faster than my 30" Bravo. Getting to old to run it on the top end to see what it would do. Age will over ride the need for speed as far as I am concerned.
