The problem with Boomsticks is that they are only one barrel, and damn expensive at that! What happens if you get an oversized or mis-shapen batch of paint, or change the paint you are firing? A new barrel is needed and thats half of your savings gone to buy another boomstick. The FREAK is the only barrel you ever need, and has the inserts to cope with this problem. Plus the full set only costs 1 1/2 Boomsticks, but does the job of 7! Amazing, and you can get seperate barrel fronts to change the overall length of it, from 10" to 18".
You know its the perfect system. All thats left is to go out and try it. Whatever you end up using, try it first.
