Dry are better for pure tooling but the new Ice is different to the old Cascade etc in that it's got a more aggressive point & first few teeth, designed with an intention (presumably) to improve its performance on mixed. Basically the Ice is fine for mixed & the sort of lines that Scotland throws at you. If you want it more for steep drytooling then go for the Dry. For water ice find an old Cascade or file down the angle on the Ice so it's less agressive. Saying that I've been climbing on none modified Ice picks all week on water ice and haven't had any problems cleaning them.
