RE: Why is lighter...."better"?
I've had relatively heavy bows in the past but now I've got a really light bow. Admittedly the light weight took some getting used to. ShorterA-A usually goes hand in hand with light weight and that causes more problems than the weight itself for some hunters.
I practice alot so I've gotten used to my bow and I ampretty accurate with it. Ilike being able to maneuver it around easy and also holding it at full draw for an extended period of time isn't an issue like it might be with a heavier bow. Sure, I hear the "kid's bow" jokes, but that's ribbing I can take. Plus,I like to a long stab with weight out frontandyou can add it to a lightbow without making it unbearable.
Here's what it boils down to for me: If the bow can do everything I want it to do I'd rather carry a lighter bow. That's just me.
