FWIW, I usually wait for something of a gap, even if it is bike lane to bike lane. Right turns on red are arguably more dangerous than left turns, since the cyclist is not crossing traffic, but merging into it, so the danger of a collision stays with the cyclist longer.
Now, if it were a steady stream of traffic and wide shoulders/WOL's/BL's, I would break with my principle and make the turn regardless of traffic concerns.
I encounter a similar dilemma at 'T' type intersections, where I have a red on the top of the 'T', with a clear bike lane ahead. I see absolutely no issue with running the red because there will be no cars crossing my path. However, I am unclear on the legality of this (actually, I kind of think it is illegal), but at the same time, it is one of those laws which does not make sense. So every time I am in this situation I am very tempted to run the red.
