By choice I use a crossbow, but when I use a bow it is an indian stalker. (shory compound, adjustable 45-55lbs ) I have 1 for me and 1 for my son. For you, I would reccomend you go to a shop like gander mountain or bass pro shop and get fitted to the right size and poundage for you. try the new stuff out on the indoor range, and see what you like, then try Craig's List for a used bow of the same type. A lot of bows go for @ $50! I got a left handed hunting bow for my brother with fiber optics, and quiver with arrows and field tips for $50. (Some lowlife broke into his storage locker and stole all his hunting gear, so I am helping to reoutfit him You may find something you can't live without, who knows?
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
