Re: Question - I need advice please.
Depends on the type of backing you have, thickness etc, but on a #4 you shouldn't really need 100 metres anyway, unless you are expecting some very big fish.
What you could do is tie your line to the reel first, then wind it all on, loosely attach the backing line, then wind it on.
If you still have room, then reverse it and it will be fine.
