Ive got a mix of both but have only done Vdiff and S routes so hardly an authority on such things. I find it easier to place double stems with one finger, single stems bend a bit more with rope drag. Im sure someone wiser will be along soon.
The 4cu's are good for the money but if you can get demons for similar i would get those(more useful in protruding vertical placements..
I like the totem cam design most. Most other things are just relatively minor variations on regular single or double axle designs.
I haven't tried demons but i have a set of 4CU's.
I'm not the biggest fan of them they feel less secure and more prone top walking to me then other types of cam i have tried. Then again this vmight just be personal preference.
Get demons over 4cu. The single stem is better in vertical placements and they will work better over time. I've seen countless old 4cus where the stems are a little twisted making the cam action not very smooth.
I don't know about demon cams but the double axle dragon cams are brilliant. They're definitely my favourite cam to use
Sensibleken i agree that the double axle is brilliant but from their its a choice between the dragon and the Camelot.
P.s if your buying a few i thing Joe browns were cheaper than needlesport last i checked.
