In reply to mmmhumous:
Petzl Nomics - prolly the second best ice tool on the market IMHO (for ice). natural swing. too bad they seem to have durability problems (gen2 & 3 handles and all gens heads). (Have used all gens).
BD Fusion 2 (green) - heavy and quite robust plus good for hard mixed, can be made to be better on ice by using the Fusion Ice pick (or similar aftermarket)... pinky-rest not so good unless you have tiny fingers. Pinky issue can be resolved by using the rest from Fuel. Weight to some extent and weight distribution can also be changed to be more favourable, by grinding down the hammer. (my tools).
BD Fuel - comes stock with Fusion ice picks and also a tad lighter than Fusions (due to being shorter and also missing the hammer). so reasonably good on ice, but behind Nomic. missing the hammer, so not so stellar on traditional mixed. (have used)
DMM Switch - felt heavy, kind of like the Fusion 2's, but preferred my Fusions more. most likely quite robust, but also really heavy. (have tried)
Cassin X-Dream - best ice tool for ice and also even better for (hard) mixed. natural swing and perfect weight distribution. easily configured to suit all needs (3 different picks with different angles and also can change the handle angle). quite a few of my friends (mainly really good climbers) have switched to these and thus far no problems on durability (1 to 2 seasons of hard use). Were I now on the market for new tools, these would prolly be the one... But due to the household having a few other BD tools, I guess will stick to them. (have used)
AA K Icer - quite good swing and felt light (but perhaps not in absolute terms). really supporting handles. quite cheap. all in all a reasonable contender, but again not readily available in UK AFAIK (have used).
Grivels - not used the latest models, so can't comment... I still think the picks are the same soft alloy, so bend easily but can also be fixed simply by bending them back.
Also worth thinking about, is the price of picks. Petzl ones are quite spendy. BD somewhat cheaper and about the same as Cassins. Not sure on DMMs or Grivels. Aftermarkets are naturally an option (Krukonogi are good but spendy, polish ones cheaper and not that far off when it comes to durability).
Oh, and one other thing to consider about the picks... BD hasn't changed picks since the X-15... Petzl modded them (so some issues). DMM has changed the picks a few times, as has Cassin. Grivel keeps constantly changing their picks.
