Eonblue - Thanks, I've been waiting 12 months for this bad boy and it looks like it will be worth the wait. The only thing I might change is to change the second, smaller can so that it could utilize shorty versions of those 50mm stems so that you could swap out the front and back chambers for even more modularity. Damn, should've thought of that before I had the piece made...
You're gonna love the Stemline, I've owned 2 in the past and I think it is quite possibly the best single chamber out there.
