VXL did think of this earlier. Here's a pic of my daily driver. The base piece was called the Hydrafoot 2.0 (made by Swagger), which frankly didn't make much sense since the "hydrafoot" is simply a glass stand. "Hydrabase" is more appropo, yet VXL is still calling the new pieces "a second generation Hydrafoot", of which mine was the first 2nd gen. So I guess Hydrabase = Hydrafoot now. On mine there are 40 slits in the large circ, but the new version's perc looks like it would provide smoother action. Mine is just a bit chuggy (common to circ's), but given my old throat it adds even more moisturizing/cooling especially with the Evolver Hydratree on top (condolences to
@newVaper420 losing his tree; what a bummer). The stem on the new piece is a little farther set away from the can than mine which is good. What I would miss a lot is the "CloudBuddy" you see the EVO sitting in; it's got a carb so you don't have to lift the EVO to clear like with the new ones. VXL should start offering the CB's again, IMO.
EDIT: I just noticed on the VXL site that it says a 14/18mm adapter kit is required. That's misleading, as the EVO can be placed directly into the Hydrabase joint which therefore must be 18mm. Why would I use tubing when a main selling point for the EVO is the all-glass path? C'mon VXL, offer the CloudBuddy again!
The second pic is in response to a query I got about what the "Vectra" looks like. It is a lighter gray than the standard unit and has a very smooth polished surface. Look closely and you can see it has a sort of swirl pattern in the finish, too. Quite nice. These were made with a different plastic composite and have slightly better heat properties and the better finish, compared to the standard unit. But this plastic was too expensive for use in the production units. There were a very small number made in several colors with a different finish.
@Stu has a red one; IIRC he posted it once on this thread.
