Gentlemen, it is the archer that matters, not the bow. I use a short bow as well. An Indian Stalker, just like the one above. It was a 16th birthday gift, and I am now 50.
The only modification from factory, is the bow cable has been replaced once, and at that time, was modified to accept replaceable bowstrings. Just like the one posted above. ( it was originally made with a continuous cable from end to end. Now it takes just a few minutes to press it and swap out bowstrings without messing with the cams.)
Quality tools can last you a lifetime, and a good used bow, is worth the investment.
I now have two of these, and loan out the second, as needed.
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.
