I want to put a bladder flat on top of a DT II, as I don't like them inside the pack and I will have other uses for the vertical pockets. I was planning to go with a standard lid and a UL Longpocket with only a 4.5 oz penalty, however, I think it will take a KU adapter kit and I don't want a "loose" fit. Going with the standard lid and a 500 LL pocket gives me better security at 9.5 oz penalty. The other thought would be to use a Longhunter, or XLT lid and put the bladder in it with a 13.5/11.5 oz. weight cost. Additionally, I have no use for the "stand-alone" features of these lids (although, I can't seem to find anything specific to the Longhunter other than 1000ci) so it would simply be for bladder/ misc. storage. Is this a bad plan? Thanks for any thoughts.
