I went with the 44/9" out of a desire for a more interesting build. if I had to do it again, I'd stick with a 30/44 and 32s. but I'd also truss the 30 and upgrade the shafts/joints inside.
plus a pair of 60s mean carrying around another, what, 800 pounds of stuff? they are heavy. :ack: and I'm guessing those bigger tires will add another 300-500 pounds.
