i too was surprised by the amazing amounts of pop in such a big slow canopy, its incredible, very much pops like an Lei when sending the kite, but still maintains the characteristic of just floating you to the apex of the jump like youre on an escalator, so smooth...
i dont think the tip tuck is a problem, its only minimal, and when it does happen the kite pops back into hsape very quickly as soon as pressure is applied on the tip that has folded..
in answer to the orginal posts of the thread:
features of Psycho 4 that were new were squared and swept wingtips, triple depower system, and the new infiniity bar
do they benefit the Speed 3
square and swept back wingtips- also feature on the Speed 3 and give very good depower and turning, minor tip tuck, but its a small price to pay for the added performance..definately a benefit
triple depower system- the speed 3 uses the same depower and bridle system as psycho 4 i believe, and definately benefits from this, tighter turning, kiteloops possible

also gives much better depower, obviously still pulls like a train with the bar out using apparent wind, but way less static pull compared to speed 2 15m when standing still or gently cruising, kite is much more manageable as to how much or how little power you can generate thanks to the depower effect...again a definate benefit
infintiy bar- i personally dont like it....centre line wear, and the unspinning idea are all fine when brand new, but seem to get stuck( spining safety) and wear out(centre line)...older bar was nicer, very simple, clean, functional and worked fantastically well...dont change what doesnt need changing just to make it look "nicer" to go with brand ner kites...i dont think it benefits from infinity bar...but wouldnt say no to having a speed 3 with infinity bar, im sure i could live with it and learn to love it
