I've only brewed with Red X once in an Imperial IPA and didn't like it. It tasted flabby (to use a wine term), under attenuated, and had that cherry flavor that clashed with the hops. A friend of mine came over one day and said he really liked it - I sent it all home with him.
My grain bill:
11 lbs Red X Malt (12.0 SRM) 1 50.0 %
10 lbs Pilsner Malt (Rahr) (1.7 SRM) 45.5 %
1 lbs Sugar, Table (Sucrose) (1.0 SRM) 4.5 %
