A bit of crafty packing should negate any overweight fears you may have by traveling with a stainless plate. Recently spent a week diving in Croatia and took the following for gear: steel plate/harness, twinset wing, drysuit and undersuit/fake rock boots, turtle fins, 12w light monkey canister light, 2x backup lights, knife, 2x dsmbs, 2x masks, wetnotes, twinset regs, stage regs, suit inflate reg, compass, bottom timer and a mesh bag. Most everything went into my hand luggage. Fins and drysuit + undersuit went into checked luggage (along with some clothes). i also took things like my laptop, power strip, hard drive, etc. My checked luggage came in at around 35 lbs. My hand luggage and backpack probably weighed the same.
