Pallet forks, which length?

42 has worked well on my 1025R. Only case I 'could' have used more was grabbing the narrow end of a 300 lb 7 1/2 foot load. I had just enough length to get it tipped and off the truck then put it down and got it from the side. Should have just thrown a tie strap around the load and fork frame then would have been easy enough to handle just from the end.
