The F6B is a tough triangle for me to figure out, too. The good thing about Heli is that they have those hash marks to keep track of where you've moved them, so if you like the general location of them right now, then just note hash marks on a piece of paper and if you get them too far away, you can always refer back to your notes so you can return them to where they currently are. And for the cross bar, a little liquid paper or Scotch tape can mark its current location in case you also want to adjust it.

By the way, how much higher did the Russell seat you? That's my biggest nag about getting one. I love sitting down low on the Mustang.
