Every state is a little different, on what you need to be legal.
When I initiate my intention to turn, I use hand signals too, but It's still nice to have that light out there doing it's job, when your hand is busy with the clutch, and no mater how good you are, your still better with two hands on the bars.
I do agree with you about the really small signals that are so popular. A lot of riders are paying a real heavy price to be cool.
Your the one that's riding it, so it's good you feel it's safe, but for me it would need two rear view mirrors, regular size turn signals, (front, and rear), A nice loud horn, and a speedo.
FYI, loud exhaust does not make up for not having a horn.
