I use the 'Snap-Off' and like it the best. It does take two hand to release it, buy is very easy to put on and can only be put on correctly or 180 degrees out, which is easy to tell. The splined ones can be misaligned one or two splines and you may not notice it until the car is in motion. The splines wear and have some slop, which may not be a deal breaker but the Snap-off has none. You choose, good luck.

I would agree with Bill. Ray had a splined setup in his car, and when I came in for a pit-stop in an endurance race, I did not get the wheel straightened out. Ray hopped in, put the steering wheel in upright (with the wheels turned). He then had to run the balance of the enduro with the wheel off abut 45 degrees!
