From the choice you have given I'd go with R6. Size is about perfect, IMHO, and it's going to take on just about everything. If going with res-c I'd probably suggest the War Dog, big enough for utility tasks an seem so be just the right if it ever came to falling back to a knife in a fight...
I would also agree that if the War Dog was included in the vote I would have chosen it in a heartbeat... <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
