It;s often personal choice, but even with me being 5'8" and a 26.5" draw I prefer a longer axle bow.
The best thing you can do is let some weight off the bow till it is smoother. Most guys that complain about a harsh draw cycle are just plain shooting more weight than they can handle. I've been there and done that.
Your bow is not going to get any smoother as it gets older. In fact, as the string creeps over time the draw length is going to get a little longer and the bow's draw weight will increase making it draw harder. It's a slow process that sneaks up on you. Keep an eye on this. Check the bow a few times a year if you shoot a lot.
