Inventory reductions tips, ie, delete Fenris and Sokolov?

I'm trying to reduce inventory and am wondering if you have an good ideas. For example, should I delete my Fenris and Sokolov gear? They increase damage for AR's and SMG's respectively and I think it would be better to have gear pieces that increase damage for all weapons, Like Ceska and Grupo for CHC and CHD. Badger (Shotguns) and Overlord (Rifles) are more examples. I can see keeping Foxes Prayer for the DTTOOC but I rarely use rifles, especially now that you can get +30% Optimum range on other weapons, like AR's and SMG's. Does all of this make sense? Do you know of other gear pieces that might as well be trashed?

Thanks! I hate being a hoarder.
