Jaydub: You started by asking about two bows. Widows are different from most other bows because they have rear mounted limbs, grip forward risers. Not better or worse, just different, than most other recurves. If you've never shot the other style, would be nice to try before you buy.
You might be able to solve your target vs hunting weight limb dilemma by ordering your next bow to complement your existing bow. If the bow you currently have is 40#, might consider getting a 50#er, or vice versa.
I,too,find that I leave most of my bows set up, and don't change limbs very often. If I have an extra set of limbs I like, I usually end up buying another riser. Good luck.
