Have to go with numbers on this one, do not understand why you would not carry both make the bigger jobs so much easier. MFB rescues carry the tirfor but have the front mounted winch rated up to 8.5 tonne with the nylon being put on the new rescue winches to bring it up from 4 tonne with the old metal cable. If you can carry them all and lot of chains, hook, slings, d shackles etc etc to go with them why not.
