Bob, get the Preston Innovations tip tubes, works on same principle as folding topkits over a lip, but individual tubes, can be cut to size and fit in holdall. A topkit carry case has to be carried separately even if you have 2 kits inside or 10 kits. Or another option is to use pole extensions to house 2 kits in each , or use a rod tube,
Thanks for your suggestions not sure what you mean with the Preston Innovations tip tubes, if I had a photo of what you are saying it would make more clearer.
I am looking in the lines of the Drennan kit case but that is only 160cm long I need 170cm the preston compact 8 top kits 170cm long which will also fit into my holdall.
Missed out on 2 both on Ebay still looking as a bit too pricey new but I am sure one will come along
