way to get back into it man! did you not have a bike at all for 2 years? I think I'd go crazy. good choice on the new ride too.
I havent gone mountain biking in around 3 weeks but I ride my 20" nearly every day. sold my DH bike last december and am taking this season of collegiate DH off. got 20th at nationals in division1 DH last year. I'll be getting something sick for next summer's mountain states cup where I'll be running expert DH. I'm thinking something like a demo 9 or maybe an IH sunday.
