I would shoot the heavier set up,, that is what I am used to,,, I get a better release at that poundage,,,, that being said,, if I was used to the 50# set up ,,,and was more accurate with that,,,,, I would shoot it,,, so choose the one you shoot the best based on your accuracy,,, not on the poundage,, they will both work,,, if the the lighter bow shoots better for you,, you can always shoot a heavier shaft from it,, which would be a nice middle ground,,
