The Mini will work, but it does have some short comings.
The fletching hood doesn't completely cover the entire portion of the fletched arrows. If you use a long broadhead, like a grizzly, part of the sharpened blade will stick above the protective hood, which could kind of get in the way. Your arrows have to be the same length. If you want to carry a couple of blunts, you have to install a device to allow for the shorter length arrows.
The one I had always seemed to be getting more in the way than it should have. I still have a cat III, but I'm not really a fan of either style.
