I actually really like the Anderson LPK, Last 2 were a lot better firing than the PSA, PTAC, Stag and Spikes. Trig is a little sharp on edges but a wet stone cures this. Other than that or I got lucky but it was a very smooth pull and Break.
I don't have a lot of experience with the others, but the Anderson FCG didn't seem too bad.
It was gritty as all heck with a mushy break right outta the bag, but 15 minutes with a stone solved that it now seems better than just 'good enough.' The RRA single stage is lighter with less take-up, but not really any 'crisper' in my experience.
