Kyle - I've looked long and hard at the Best Tugs products and they are excellent - on that point we can agree to agree vehemently!
Where our opinions diverge on performance of a "tow" vs a "lift and tow" tug is almost certainly based on experience, and those experiences are almost certainly very different based on geography and climate.
The Alpha would be pretty much useless in the environment in which I operate. It's wheels offer little-to-no purchase on ice nor an up-slope covered in snow. Similarly, the small diameter of its wheels would be presented with a severe challenge in entering my hangar over the big crack which appears as a result of frost heaving in the winter. That crack can grow to 3" of vertical displacement of the asphalt - that's literally a 3" curb the tug has to overcome. It's a significant challenge even for my AeroTow which has large wheels and the weight of the aircraft nosewheel to aid in traction.
Suffice it to say that one should purchase a tug after researching the options available and comparing them to the mission at hand. Each of us will have a different mission. Old Man Winter has a nasty habit of taking a relatively simple mission and contorting it into the mission from, well, an unpleasant place. Unfortunately around here, Old Man Winter is a factor with which we are forced to deal for several months of the year...
