The most important thing, and the whole reason we're doing this at all, is because we like to shoot bows and arrows. For me, that doesn't mean I like to shoot any old bow and arrow, or even all of the ones I own. When I grab a bow to go out and shoot in the morning, it's because I want to shoot that bow, not because I think it would be good for me. If you wake up in the morning and feel like shooting the 40# board bow, shoot it; if not, shoot your other bow. If neither one of them makes you happy, then like most of the rest of us, you have to dream and connive of a way to get a higher quality 40# bow that will solve all your problems and make you happy for the rest of your life (HA!).
