I shoot a WS-66 and I must say that I have yet to see any major curves from it when not held perfectly vertical. Also, you do not want to shoot small paint out of the WS-66. I normally shoot Zap Chronic which tends to run about .690 (bore size is .691) and have had much better luck with it than smaller sized paint such as Evil or Marbs. Obviously being consistantly round and of similar size from ball to ball is important as well.
Currently, I run my WS-66 off of CO2 in a remote set up with a Palmer Regulator mounted below the grip. With this set up my velocity varies +/-3 fps.
My understanding with the concept of how the barrel works is that pressure at the top of the ball is less than at the bottom because air is allowed to bypass the ball in the three upper channels. The increased pressure at the bottom of the ball accelerates the bottom of the ball faster than the top. Remember that a Flatline's Barrel is not super smooth inside but rather "pitted" to allow it to grip the surface of the ball better to impart the backspin (and that over time as this finish wears off the affect will lessen requiring the barrel to be re-sandblasted by Tippmann). The Hopup barrel is not like this at all and is totally smooth. Thus it is my belief that the Hopup barrel is not relying on the ball being pushed up against the top of the barrel as the Flatline does.
On the issue of alignment, the Hopup barrel has a groove cut into the outside of the barrel in the back. This groove is perpendicular to the barrel itself. When the barrel is inserted into the WS receiver, a stip pin is inserted to align the grooves. Then a screw in the receiver is tightened to "Clamp" the barrel in place to prevent barrel wobble. However, it seems there have been some manufacturing issues and the gooves for the strip pin have not been placed in the right location thus requiring owners to self align the barrel's hopup gooves. Once this issue gets resolved alignment will not be a problem (My barrel's groove is in the right position).
While the barrels are listed as being available sepreratly it seems production of the barrels matches the production numbers of entire markers thus every barrel produced seems to be going directly to building complete markers. There have been rumors however that barrels may soon become available for seperate purchase and when that happens it would only seem to make sense for someone, if not Warsensor/Armotech, to come out with a simple screw on clamp adaptor for the barrel.
Just as an example...this is a day I was sighting in my red dot. The marker had not yet been fired at this distance this day. Paint was a bit old and had some dimples but not too bad. The guy firing it has never fired the marker before. The shooter was prone using the bipod for the shots...

which barrel lenght do you have? 14 or 20. I gotta start saving for one of those
