I would second the martin products but I dont like the hatfield in particular. A hunter or the mamba are a couple good bows albeit one pieces. They hold there value pretty good used (its hard to find one under 150 in good shape with no limb twists).

I would recommend a curve for sights. Also going to the lighter weight as Stealthy recommended, but I think 40 would be a little light for ya and 50 would be the tops you could handle. You will get comfortable with it over time but the dedication to shooting this style of bow is needed otherwise you will hit a plateau in time. I also agree that shooting instinctive is the way to go. That or learning to gap/split vision shoot. Once you learn it, its not very far off from a sight pin and with consistent practice you can get VERY good at it. Byron Ferguson's book talks about it (become the arrow). Carbons will work out of any of the bows, becarefully of the weight though. The bows will fly around like mad in your hands with a really light arra and you could end up tainted as to how trad shooting really isnt (hope that made sense <img src=icon_smile_wink.gif border=0 align=middle>). Hope that helps some....
