I've got a 56 inch PSR and love it; it's my go to bow. It's butter smooth to draw (I go closer to 29 than 28 inches) built like a tank, zips an arrow, and is just a flat out fun bow to shoot.
I'm going to be picking up a second Widow in the not to distant future, and while everything else they make looks very nice to me, at the end of the day, I suspect that a 58 or 60 inch PSR will find it's way to my house.
Perhaps not the best bow to use for competitive shooting, but for being in the woods, it's about the perfect bow IMHO.
Some folks love it (me for one) some not so much, I'd defiantly recommend trying one before you buy one.
