Reply to Any Drummers/Ex-Drummers out there that produce now?

Hey guys been playing the drums for going 15 years now and moved onto mixing when I moved to Uni because I couldn't bring my set with me. I have a question for anyone here who used to drum and now mix's; has it affected your mixing skills?

And more importantly to me at the moment anyone here tried to produce with a percussionists background and no traditional music theory? As i'm sure most of you know that drum music is written different to all other types of music and thus I don't know anything about cords, key's, scales etc.

Should I be learning an instrument (piano) or just reading some music theory books?
