siouxsie,
Drozd is doing it the same exact way I am and have told you to try it, looks like he is using a bit bigger of the 306 piece then I am but still the same darn thing, it works great and you can use any size 510 tube you want, reg,XL, or even one from a CE2 carto, and or zip it off at any size you want, and you can use a drip tip of a stock soft tip, this is quite easy to do, Good pics Drozd
