All I know is I got beat by a guy on 27.5+ bike this weekend. And he's a large human. And there were lots of tire-eating rocks in a number of the stages. Basically, what i'm saying, is every "theory" I had about 27.5+ just got crushed (great for beginners, large guys can't use it or they'll flat by just looking at the tires, isn't fast, isn't fun etc...) Choices are awesome, but now even *I'm* overwhelmed. Back to the drawing board? Maybe. Its the artist, not the brush, I get it. And yes, this dude has even done well...
