I bought a 28" bag. It lasted me two trips; then I went out and bought a 25" Delsey. With the weight restrictions, the 28" was just too heavy even empty let alone when I filled it. Take the 25" or 26" and than you can leave the worries about it being overweight at home. Makes travel much easier.
I guess I should add that you wouldn't need to worry about a 25" bag being overweight if you just packed clothes. All bets are off if you're packing your dumbells.
I can't do 62" being my exact height. It would be too cumbersome.
