Weird, The Airtechs where my first crampon purchase 7 years ago and I still use them for easy mixed and winter walking.
A few years later I bought some b3 boots (Scarpa phantom guides) which had a lug on them so I thought oooh I'll get some poons with a wire toe bail on them to look a bit wee woo... and to feel confident in my gear
Here started my near obsession in getting a crampon to fit my boots properly. It got to the stage where I was swapping wire bails, front and back sections to and from Petzl, BD and Grivel, I even had 2 different wire toe bails from Grivel. The only ones that I thought fitted my boots perfectly was the petzl dartwins but they where too technical for my punter grades and I didn't want any doubts creeping in when i was walking out down a grade 1 route as I had read that they where awful on snow plods.
Which I suppose comes back to what Stuart the postie was saying if I'd of spent the time messing about with crampons on perfecting my footwork all of doubt and stuff wouldn't be there because I'll be honest here atm I wouldn't like to second grade V ice with my 7 year old airtechs on.
Do I think you would benefit from more technical crampons climbing grade V ice? I would say yes as it's already in your head that they are not suitable and as we all know winter climbing is a lot to do with your head.
I know people will say that I know a guy that went up .5 with slippers and a tooth pick, Harold Raeburn went up green gully with hobnail boots and a tweed vest but things have moved on and personally as a pure punter I will gladly take anything that makes my climbing more enjoyable. Or am I a salesmans dream???
Good luck with your choices
cheers
