Longboard curly leash?

I’ve got a springy coil leash for my 12.6” SUP - bought to keep the leash from dragging in the water or getting tangled underfoot.
I was thinking about using it for the soon to be acquired longboard…I doubt the weight and size of a longboard will allow it to be sprung back into me like a short board could.
Anyone tried this?
