I have a set of the RMC optic fiber (2 rods in the back and 1 in the front) and I don't like how small the front bead is...too small of a diameter for my eyes. I want to change them out and am not sure what I want...thinking about
-williams fiber optic rear & front but that may not be any better
-williams or lyman peep, but not sure what to put upfront that will be a big enough diameter and want to ensure the rear aperture is big enough for me
-lymman hunting sights with a white front bead and basic dovetail in the rear

Thoughts? I am interested in any suggestions along these lines or others you may have (NEGC...again with a big enough front bead to easily see and center and for a TC renegade.
