Here's my opinion:
I'm using one on my MCX nytro with 162" powerclaw and 17# boost. I really like it and have zero complaints. With the transfer blocks in the no-wheelie position, it keeps the front down really well and is very controllable. The only time the front will lift up a little bit is if I hit a mound or come over a rise at full throttle. It also rides great.
My sled is the blue nytro on KMOD's website. That photo was taken two years ago with a prototype skid installed. The production skid has a lowered ride height.
Based on my riding style, experiences with the KMOD skid, and my sled's setup, I would definitely buy a KMOD if I were to build another T-Nytro.
