Sort of a sad postscript to my earlier post. I used the IT as I described above, hooking it to my golf bag with a connecting device. Great so long as it worked, but the strain on the IT's thin tubes eventually caused the extension mechanism to pop off one of the stops that locks the handle in place on one side. My earlier comments about the lightweight construction and efficient use of the space within the bag remain unchanged, but I'm afraid my concerns about the durability of this bag were well founded--you definitely don't want to check this bag.
