I'm in the grumpy old man, dyed in the wool category. Probably somewhere between 2 & 3,000 days teaching, racing, playing, patrolling on teles - which is a bit hard to believe really, where did all that time go?
I skied exclusively on 3 pins until the early 90's when I moved to plastic boots and was reluctantly forced to go to cables.
I still ski patrol on teles - well did until my current Garmont EnerG exploded the bellows the other day, ripped the middle bend apart. Bummer.
I like a relatively narrow ski (currently Volkl Racetiger 76mm underfoot, fabulous on packed or hard, bit of work in soft but anything turns in that so who cares), soft flex boot (was Garmont EnerG with I guess a couple of hundred days on them) and absolutely the least "active" binding possible (currently 7tm with the powerbar removed - work requires release bindings, play does not).
I always found the Garmonts to have the nicest flex in the past so am guessing the Scott might still be the softest out there?
I've stayed clear of NTN because I just can't believe I'd like the feel of them. I see so many people on tippy-toes on them and hear so much about how "active" they are that I reckon they'd feel like some diabolical marriage of the worst of AT and Telemark - heavy surrogate alpine system half holding your heel down but with the disadvantage of a free heel. I'm not averse to alpine (also used to instruct that, and do it increasingly these days when my knees decide it's time for my back to have a turn at hurting) but I like tele to feel like tele, and alpine to feel like alpine. I started teleing in the first place because I hated the feel of AT gear.
My ideal setup would be a plastic boot (for waterproofness) with a flex like a well used leather boot, the binding "activity" of a three pin but the edging stiffness of an alpine boot. Oh, and it should weigh the same as my skate boots

I'm intrigued by the idea of the Bishop BMF (not so keen on the weight though), it looks like it might transfer some of the edging torque from the heel through to the ski, rather than relying totally on the toe and bellows. Not sure if that's the case?
Any comments on the comparison of boot flex and feel NTN vs 75mm?
Cheers
