NEVER USE HAIRSPRAY!!!! It will gum up your chamber and it is one of the LEAST powerful fuels. Axe works fairly well. Right Guard DID change so that it NO LONGER WORKS, but the long supply chain of many stores still has the good stuff. Use Static Guard. This comes in a skinny can with an orange cap. This is one of the best. Way better than good Right Guard.
As for the ratio, I prefer 1.5:1 C:B. This does have some noise to it, but I dont like guns that are too quiet. Other ratios do work better for efficiency and stuf like that. When I am going for quiet, I choose a pnuematic.
My Pnuematic, which is a product of the "quiet tree entry pnuematic topic", is very similar to this http://www.antennalaunchers.com/csv19/index.html
It works fine. I used converters insted of endcaps and 2" barrel instead of 2.5"
