I'm leaning more toward carbons these days. For my trad bows I like GrizzlyStik tapered carbons, and I use feathers only for the trad bows. Broadheads come down to personal taste, but you do want a good cut-on-contact head. I like Magnus Snuffers and G-5 Montecs,and you might get the idea I like 3 blade heads.
As for sights, never used them except on a compound, and I even shoot the compound "instinctively" now, so I can't help there. [&:]
