I would do some research on head tube angles with the totem. I am running 66 degrees with the fox van 36rc2. I'm not sure about axle to crown height on those but with an extra 20mm of travel that may make things more slack than you are wanting. There is also a risk of voiding the warranty if the fork is too long. Have you heard about their Lucky coming out soon? Its 7 or 8 inch with the same suspension design. 1.5 head tube also so would work great with the totem.
Followup on my ride. pictures are above and its now got probably close to 1k miles on it. I am now a Canfield whore. I can't say enough good about the bike. You'd think I had paid endorsements the way I rant on about them (hint hint)
The suspension is super supple and ramps up just so perfectly to prevent bottom out. I take that bike everywhere and I don't think I will every take its performance for granted. It still brings a smile to my face and manages to impress me even after all those miles.
One thing to note that bothers some more than me so is worth mentioning, the paint is holding up super well. Resisting chipping and scratching. There is pedal feedback with this design which is part of why there is no bob when climbing. Your pedal strokes pull the rear wheel forward and down. Locks up with the ground and gives incredible traction but will pull at the pedal going over large water bars and such. A tradeoff I think is very worth it.
Bike is the stiffest I've felt laterally ever!! You cannot flex this frame and you'll notice the precision and cornering right away. Stiff, stiff, stiff.
