I realized that I played much more controlled and economically on a five or six but went nuts on a four.
This is part of why I play my 5 more recently. My pop playing was too busy (even though I'm faster on the 5) so sometimes I gotta put the 4 down and chill.
Also I can't stand guitar player's who tune down 1/2 or singers who want to lower keys. This makes it easier.
