Hi! I'm trying to make my first saber. I'm inclined to use the MHSv2. Besides the fact that I haven't found a good presentation about it, I can't understand how it works without a main body. Am I supposed to use just extensions? Given that MHSv1 main-bodies are 7", and the longest (and unavailable) extension for v2 is 6", I wonder if this was a design choice of the thinner profile.
