I really like the Rockshox Maxle Ultimate thru axles. They are pretty pricey though. DT Swiss thru axles work really well too and are definitely not fiddly, but because they aren't quick release they can be a pain if you remove the wheels often.
The specs you list seem odd to me. As far as I know these things are fairly universal, but I could be wrong. Most use 15mm x 100 thru axles front and 12mm x 142 rear right?
I just ordered a Kinetic traxle for my trainer and the specs you give are in line what they had on their site for a Roker. The12x142 mm is the space between the drops and hole diameter, the 170mm is the axle length 1.5 is thread pitch. What is the #16 representing?
