Well it really depends on how much you have of each? And what do you want to set your sights on more!
Move reel bodies only (no spools) and more clothes to carry on, reduce any unnecessary packaging.
Clothing amd spinning reels with out spools are going into the carry on bag.
The vertical jigging and fly fishing reels will be checked in.
I have pulled some jigs a popper and a stickbait.
The 4kg's extra will cost me $340Aus from Jhb to Sydney via Dubai.
I have will pack again the morning and then make the call if I will bite the bullet and pay for the few extra Kg's
I am sure there will be no issues coming back with extra weight after 8 days fishing...
