I just purchased the SI Ballistic M Frame 3.0's and love them. But i have several lens that i need storing (clear, grey, persimmon, VR 28 and a Prizm). What would be my best option for this? Is there a case out there that would work? The case that came with only stores two additional lens. Maybe try and find the old box case and cut the foam for extra lens spaces? Any help would be appreciated. Thanks
