FWIW thats exactly the kind of music I play and use BIAB for.
Sounds like you have the basic ProPak or similar - please confirm. I have Ultrapluspak and there is NO shortage of 50's / 60s RTs (I try not to use midi). Plenty of Styles to go at - 12-8 Styles, Surf, R&R, Twist, Shuffle, Boogie etc etc. AND - if one isnt there that works for you specifically use Stylemaker to make one up from the thousands of RTs - thats what I do.
I DO think that BIAB is quite Jazz / Latin orientated but there is still a wealth of RTS that are NOT of those Genres. AND - some of the new "Crooner" RTs work very well in 50s/60's ballad tracks etc.
Hope That Helps
