Looking at getting some new cams. Thoughts on the relative advantages/disadvantages of single or double stem cams? I'm looking at the DMM 4CU or demons off needle sports. Pretty similar prices so tossing up which to get at the moment. Any thoughts or advice welcome.
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.
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.
