In reply to Phil79:
I have a set of peenuts, they work OK but I don't place them that often (used mainly on slate and a little on lime and less so on grit). I've certainly not had a problem with them being too hard or lifting out of placements. The sit on the same biner as my RPs and BD swedges, they seem to complement each other OK.
However I'd agree with those suggesting waiting for the new DMM brass ofsets. I don't know for sure but I'd guess they'll be stronger and I do prefer brasses.
In the same vein I much prefer the RPs to the BD swedges.
