I had a Mach 6 and now have a Trail 429. Love both bikes If the Switchblade follows the above leaked geo/stats then I think it fills a gap in the lineup for Pivot. The Mach 6 is great for super chunky locations i.e. Desert Southwest and East Coast Big Mountains like Virginia and NC. Trail 429 is perfect for probably 80% of riders and locations in the USA. For me I spend time between Coastal CA, Tahoe, Downieville, Rocky Mtn and Desert Southwest. Think the stats on the Switchblade will present itself as a Swiss Army Knife for me. Keep in mind I'm not a 29er hater. So bikes like the Santa Cruz 5010 do not make much sense to me. If you are going to go with short-ish travel because you are doing more epic/aerobic riding, then I think you should go with bigger wheels. At the same time, I get how you might want a bike with more trail feel but the ability to get the 27.5 wheels off the ground. We are lucky to have so much choice. Wonder if Pivot will make a competing bike to the 5010 or the Transition Scout. I've ridden Specialized 6Fattie FSR. Not sure I am sold on the mid fat tires for full suspension. If the tires are too firm they skid out easily with the lower profile treads. If they are too soft they bottom out quite easily messing up the rim etc. I don't think the wheels and tires are there yet on the plus gear to go as big as full susp. will let you get away with. I like plus tires on hard tails because I think it allows you to go bigger when you don't have the advantage of full suspension. If I get the Switchblade I will immediately sell the stock DT Swiss Spline 2 M1700 29er wheels....so lame they keep using this XC wheelset for all mountain bikes, and get the Ibis 938 aluminum wide rims to run 2.3x29 tires with a wider profile.
