The problems of the old skids are long gone. The live axle slides are a waaaay better design and the center of the rails are raised to prevent caming over. They extended the c to c on the 159-162 skid and the 174 was built with a 32" c to c. I ran the new live axle skid with Airwave shocks for the last 1.5 seasons with zero issues. The rear air shock doesn't stack up like the old fox/ohlins shocks that the old M10's/CR10's came with. This is what caused the rear cross tubes/shafts to bend. They have a slick new adjustable limiter set up this year, looks like it will work great.
Just installed my new 162 skid that i bought from Trevor, i know of all the changes over the earlier skids including the new air bag for the front shock (yet to be released) however i am not familiar with the new limiter. Have you got any pic's of this set up. May have to phone Trevor to get the skinny on this.
