Sounds like you have the right approach to chords. Typically, how many will you try to switch between?

I've gotten a lot better at A major... Lucky, i have skinny fingers, can't imagine how people with fat fingers do it. I think the one barre chord that I have the most trouble with is F major.

I agree, I like barre chords. Well, the E shaped, I agree the A shaped barre is difficult. I just found this out the other day, but you can use ALL open shaped chords for barring. I thought you only used E and A major and minor, but I just found out you can use them all. Same theory applies for each

Visio is a Microsoft tool used for flow diagrams, flow charts and things like that.. All kinds of stuff like that... I have created my own steciles for the application. I have things like fretboards, notes.
