RE: your first bow
My first hunting setup was a bear polar 2 from the mid 70's An early compound that had 4 wheels. I still have it as I've killed several deer with it and I'm kinda attached to it. Plus its not worth much more than memories for me.
The bow was actually way to long for me when I got it. and still is realy. My draw was right at letoff so I had to hold the weight untill I got bigger. I shot my first deer with it too.
