The B6-4 has the lowest Dv for the IT version, but the B6-2 has good Dv numbers for the RT version. However, using the -2 in the IT version has very high Dv numbers, as does the -4 in the RT version. There is no "compromise" motor that has safe Dv numbers for both scenarios. The wimpy A8-3 might be a good starting point, though, as long as the parachute opens safely.

I think I'll reef a new parachute tonight, just to be safe...
