I know John I'm just waiting for the "UBER" density curves for Storage with "Specific Application Storage" Heads, you know when they're no longer specific application, but the "storage standard heads". You know they start @ 0.30 and go up to Oh lets allow some room for growth so let's say 2.00 GPM/SF.
I just started down this road a question Craig had an OH occupancy that was done with 4.2K heads, it didn't say storage or not. Just 4.2K. Then Ron was talking about TYCO Literature or Listing appeared to allow 4.2K in OH, so I was making a point that for some OH applications 5.6K heads that are OH listed are not allowed. And Now we're here! Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.

(I know not all storage is necessarily OH) Are we creating a new category? LH, OHI, OHII, EXI EHII and Storage? Not that I think that's a bad idea.
