In the nicest possible sense you are talking rubbish when you say that Euro guns can't take 2 bands.
Rob Allen is a eurogun and is designed for 2 Bands same with most euro guns the muzzle is made to take screw-in and circular bands.
It is possible to buy rubbers down to 14mm and 2 of these would certainly be a lot easier to pull than 1x 18- or 20mm band
They would also provide enough power for most fish.
I would look at spreading the load over a greater area Alison, perhaps a plastic/fibreglass loading pad that is something like the RA one but larger?
If you have trouble loading from the hip due to slippage maybe one of those rubber blocks that sit on the belt and catch the speargun butt?
