Lol. To be real honest, the customer base has a lot to do with Poo's reliability issues. IN GENERAL, Doo guys tend to be a little older, little more methodical in our riding, and spend more money on the sport. (In GENERAL, nobody get panty-wadded.)
Poo guys tend to be 20-somethings, and ride like they just don't care. I saw a rig in the shop yesterday, a 14 Pro, missing about 10 lugs, broken track bars, and he "didn't know how that happened." Same guy had a brake fire, "didn't know how that happened." He also had mismatched a-arms throwing his camber all out of whack, a scratcher torn off, and bent steering post. After the fire, he couldn't figure out why his brakes didn't work. He was perfectly happy running it into the ground. See a lot of Pro owners like that.
Pros are also about $3000 cheaper than Doos right now.
I rode with a guy on a Pro the other day, he was WFO all day long, swamp, hills, feet flying off the back, it didn't matter. I could totally see how he would kill an engine in very few miles.
Buddy here is a 20-something Pro convert to Doo, he likes it, but he has hit two rocks hard in 200 miles, and he rides his Doo like a Pro. I will be curious to see how his holds up.
I am a Doo guy, but the first to admit that performance wise, the Pros are the sleds on top right now. (At least up to a certain, uh, 170-ish track length.)
