Whatever gets it done man! If a sight is your thing so be it. I have one bow I put a stabilizer on (an all wood hunting bow) and I get alot of stink for it , but I can hit consistently at 30-35 yards with that setup on 3d.
Anyway, I think if you like it you should do it.
Might wanna think about gap shooting, it's like having a sight, and once you get used to it, it's like everyone's bow has a sight. You can pick up your buddies bow and shoot it like you own it ... .just something to think about.
