Are you going to be running around with AGG HK gear on as well? Pick a barrel that works for what you need. Stiffi's are great and all but they are set to one size so you need to by many of them to get different size bores. If you want a good barrel go with one that will be versatile to the fact that you use different paint. DW Fibur, Dye UL, Shaft kit and so on. If you want to waist your money then fine buy some cool looking AGG barrel and i will laugh at you the whole time, as your paint fly's around all over the place and i one ball you right in the grill.
