      Thanks so much! I've looked at SMTCOMP results before but still been a bit lost. Good advice on sticking to smtlib format - I was lazy and the Python interface was tempting. But I've seen most of my workload turn to bitvector stuff so CVC4, Boolector and Yices seem worth trying.

      For CVC4 with bitvectors you will probably need to tweak it a bit for reasonable performance. For non-incremental problems I'd recommend --bitblast=eager --bv-sat-solver=cadical. (But I'm sure @ciphernyx can give more detailed hints. :)

          Cadical is a good shout, eager YMMV depending on how heavy the bit vectors are and how much Boolean structure the problem has.
