I think on small inputs the difference in LA time isn't enough to be worth much programming effort, since it's more complicated to use a hybrid versus cado-as-black-box-factorer. I don't bother to break CADO to invoke msieve for LA below 150 digits, and by that size lots of folks aren't using YAFU anyway. msieve may be 2/3rds the time, but the matrix time for a 130 digit number just isn't that long.
