Do you want a single or two-stage trigger? Perhaps a better question would be: in what type of AR will this go into?
Light pull weight or more of a standard (i.e combat) trigger pull? I understand you said you're not worried about it being very light, but its not very clear imo.
Standard (curved) trigger bow or a flat bow? Only Geissele offers that, which I think is a fantastic feature.
If you can better define what you need, you'll get suggestions that better meet those needs.
