I use Nevegals 2.1 front and back. Stickee up front for grip and the dst in the back. I like doing stuff where i need alot of grip so i love them. My buddy has the Panaracers 2.1 and loves them. But what i did notice is that they are "ALOT" smaller than my Nevegals of what are suppose to be the same size. The size difference is incredible. So maybe thats why they seem to roll so much better. their 2.1’s look more like a 1.95’s
