Actually just got a set of 22" Pulse. Only about 10mins. of seat time so far but I like them. They measure 21" tall, lugs 5/8", 1 3/4" space between rows of lugs. Lighter than my Rzr 2's and Klaws and a softer compound. Straight line traction is great, not sure about their cornering compared to the Rzr/ Holeshot pattern though. Need more ride time.
