Still just a bit stumped.

[Lyle Raymond]

Thanks for the assistance with my chart thus far; now I have two questions 
remaining.

1.  How can I increase the legibility of the chart by expanding staff sizes, 
etc., especially the chord names?  Jazz players would no doubt appreciate 
much thicker chord symbols.

2.  I'm still getting a funny "tail" on slash noteheads.  How do I fix?
