I'd personally get both motors. The RMS 24/40 has several great loads, my favorite are the D15, E18, and F24. Don't knock the 24/60 till you try it. The F35 is an amazing load, and I personally like it better than the F24. The F62 is a beast with its dark smoke!
I really wish Aerotech came out with their 24/80 and 24/120, I actually got to hold a prototype 24/120 motor. With CTI requiring hazmat, and the loads I want being hard to get.. that's just a missed opportunity.
I have a rocket where literally the CTI G65 is the only load I can fly it with, because all the other loads are HPR, cant fly them where I fly, and the only vendor that I buy from that has G65's, doesn't have G54's, but the other one does... but I am not going do two hazmat orders.... ugh...
