I rode 9413 on the B1 3 weeks ago, it ran fine, didn't get above 25 but it wasn't horrible. And the B1 does tend to have more RTS's from my experience. The B36 is semi spaced out, the ratio of RTS's to XD40's is about 3:1 or 4:1. And the B3 is even somewhat, and you cant say the B3 doesn't run frequently because it does, it just suffers from severe crowding and bunching so the wait times are astronomically long.
