In reply to GarethSL:
> On the krukonogi picks, they are brutally strong but quite prone to rust iirc. Very popular in the dry tooling/ competition world. Apparently made from tank armour or something, as its eastern European its probably from a melted down T34...
Indeed, quite popular for those doing competative drytooling/IWC stuff.
And pretty sure Armot Steel ain't from tanks... I would not however place one anywhere near your gonads or a geiger counter.
As for the OP.
The best mod to make Fusion IIs stick more easily onto ice (without breakin' everything) is sadly to shell out for them new Fusion Ice Picks. The gentler pick-angle makes them work more like a Nomic (1st time sticks).
The next one in line is to also make room for the pinky (or get the lower handle part of Fuel) to allow more wrist-flick actions.
Adding weight to already heavy tool really is counter productive IMHO and not needed.
Fuel (with the more gentle pick angle) climbs almost the same as Nomic from my experience.
