Ive got one, and its great. I love the versatility of it. On full travel copes with anything that I can throw at it (and im a 13st duffer), yet it is light and can deal with full day epics no probs.
When I come to renew my full suss, I would defo think about another Genius.
Only had the shock serviced once, and it is a 2008 model. Still runs like a dream. Rear shock servicing is not a prob, Hope service them, you just need to post it to Hope.
