wow i almost though you had answered your own qeustion, as the second poster has the exact same avatar as you xD
Anyway on topic, i made a similar topic about this, and i gotta say it comes down to your height probably. I myself am rather small, so i had to make a decision for my second saber, i went with 32"even because i knew 36 was too large to be effective. It comes down to height and prefference, and maybe even some experience with the lengths. And ofc what you want to do with it =)
Good Luck!
CbrS* lol that pretty funny im about 6 foot 6 foot 1 but im really good with a saber and i dont want a long blade but at the same time i do want one so im really undecided
