RE: Pros and cons of axle length
If your PSE is 10 years old, I bet its around 42-44". Your in for a nice surprise.
I am all about longer Axle to axle, but 44" is a bunch to manover. What's funny is my commander is over 36" and is consider long.
Biggest pros of longer bows is string angle, stability, finger pinch (for finger shooters).
