I think the LJH017/JH018 is just shaking me two different ways. Its been tempting me for awhile and just looks real nice xD
However, with the new ratchet perc rig

I've seen vids of both pieces, and they recycle similarly. The JH017 has like two extra recycle elbows, a male joint, and an inline (suddenly it sounds so diff, but from vids sake they seem to be about equal in being drag-free, recycle-ready, and not over-perced).
Where did you find the videos of them in action? Can you post them?
