I went from a Nicolai Helius CC (5.25" of travel at most) to a Cotic Soda about two years ago. Don't regret it one bit, in fact there's no other bike (except my 29er) that I'd consider riding instead. I've got 130mm fork on the front with a lock down (DT Swiss), and 2.4" tyres.
For the people I ride with and the trails I ride on (Brecon Beacons and S. Wales, mainly) it performs brilliantly. It's comfortable enough that I can ride it all day and I'm not any slower on the descents than I would otherwise have been in the Nicolai (i.e. I can still keep pace with the people I ride with on full suspension bikes). It climbs like a dream too. Big benefit to me at the time was reduced maintenance for pivots/ shocks. The transition from 5" of travel to hardtail wasn't anywhere near as difficult as I thought it might be either.
In all, I can't fault the Soda. Also, it still looks as good as new two years later. Get one 🙂
