I have a 54" Pika, 50#@28 and my DL is 28.25". It's an amazing short hybrid. Quiet, fast, and one of the smoothest drawing bows I've shot. Slender limbs that make it seem petite, but it just smokes an arrow. I have a static limb recurve that's 48#@28, and the Pika draws easier and smoother than the recurve. I don't feel any finger pinch or stacking whatsoever. It's size and maneuverability make it a great hunting bow, and I would recommend it to anyone.
I haven't shot a Fox, so I'm no help there.
