too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
They're all roughly the same functionally, so price might be the biggest consideration. I like the compactness of the ends on the Yakima, and it has nice safety latches, but may lack versatility on some low bars. (that's may, because I'm not sure it will matter).
Whichever you use, be sure the seatpost clamp is secure, since the bike in hanging by the post with no backup if it slips.
