Hello guys. Hoping for an advice from expierenced lightsaber builders on a PC tube for a blade. There are basically 2 types I can buy, regular one with flat surface inside(thats what i've been using so far) and there is another type with corrugated surface inside...claimed to better diffuse light. Keen to try it but wondering if anyone already used second type and knows for sure if it's better or worse in terms of a lightsaber blade.

Hello,

I have bought a lightsaber blade with the faceted surface (lengthwise) rather than the traditional round ones we normally use and it was terrible. It just didn't diffuse the light correctly, resulting in a dim, dull blade.

I've never seen corrugated before though. Can you post a link to the product you are asking about?
