I'll be flying for the first time with my guns in May. I have an old Plano case that will fit the luggage size requirements for my airine, but when I got the case, the foam was beat up. Somone had picked most of the foam, to where it's not usable. Any ideas on where I can pick up some cheap foam? Honestly, I'll probably have my guns in cases, because I'll need them for compitition anyway. Just looking for some egg crate foam or similar to squeeze some stuff in there tighter.
