Honestly, I'd be willing to bet it was primarily due to dead legs after skinning. There's riding and then there's riding after major hiking or skinning.
I'd ridden on Voile sliders and haven't noticed a huge difference in terms of riding ability. However, after a few skins up, I'm riding like a flailing fucking idiot. It isn't due to the equipment, it's due to my legs being fucking shot.
