Hmm... a little weird on the poll, since:

* I build both "Jedi" and "Sith" sabers... although I never really think of it that way anyhow, since the color doesn't always determine the wielder...

* Although I USED to use solely thick-walled blades (BOP I & BOP II)... I switched to thin back in late 2007 (mainly for what was going to be BOP III), and never looked back.

So... I guess I'll have to go with no vote here... but--yup, I told y'all what I do. Thin-walled these days. Although I have two or three nice thick-walled blades if I ever wanna plug 'em back into the Flange III (and IV!) sabers someday.

Finally... if it's a question again that n00bz might ask about... both types are extremely resilient to damage, and even though I'd not recommend pitting a thin-walled VS. a thick-walled for dueling an opponent (as in you have X, he has Y)... it's not all that bad unless one of you is going completely out-of-control + insanity + hogwild + roid rage...
