I like small boutique brands just as much as the next guy but with only 150 units I'd be worried about parts availability when shit breaks or if there a common failure point with the frames. Also the motor bulge on the Crestline is worse than the Levo and the down tube looks massive. I hope the new Levo looks more like the SL, no motor bulge or ugly shock stay. Santa Cruz knocked it out of the park with Vala, it's easily the best looking EMTB out right now.
I might be biased but I really like the look of the SL over the Vala. In person the downtube and crank area look pretty bulky but not bad.
