We have both but my preference is the Pro 5.0. Wishing now we had bought another Pro 5.0, but instead got the Tri-Ax for the 01. The Pro 5.0 is just tighter, firmer...and yeah, it's shorter...it's supposed to be! If it ends up being to much of a reach for you, the Tri-Ax handle bolts right up and is less than $30.
