I was able to go directly to Bobby's to pickup my my Longfields, and got to see his shop and have a one on one explanation about how and why he makes them as he does. I chose to put mine in early, having busted a stock birf and knuckle playing around in some dirt piles and ditches on a little course we built at the back of our church.

The Longfields are about the only thing I don't worry about breaking. I run 37" tires, V6 with 223:1 crawl ratio, so I've got all the criteria for breaking stock birfs. I have backup birfs, but I don't carry them. I would on a remote trail run, where getting back might require them...
