The apogee is a joke though,
600X series were better, and by a decent amount in lowflow situations.
I hate how it always seems like there are only two options:
-Impigment or semi-impigment blocks (storm, nexxxus, aquaxtreme mp5)
-Apogee

There are alot of blocks that make a compromise between semi-impigment and "apogee"-design (mostly from germany), there are the 600X's, who should be back in production IMO (yeah, keep on dreaming Jochen, like Swiftech will ever admit they hyped the apogee, just to be able to release a new block on "old" technology)...
