Rear tire choice is riding-style specific in my opinion.
A trail rider that is concerned with forward traction will probably like a Holeshot/Razor/etc....more than I do. They work very well in various terrain, but for me, they slow me down because of way to much sidebite.
A faster...sideways kinda rider will probably not like those choices as much. A Turf Tamer/C-826 will work better for kicking the rear out while still getting good forward traction in many terrains.
I'd rather have the stock rear tire than a Holeshot.
