I assume the 181M plus braid will fill it to max capacity, isn't it still the done thing to slightly under fill when using braid?

Look up pattaya fishing.net advanced fishing line calculator it works well. I calculated it to 181m. You need to find how much line is put on by 1 turn of the handle.

but don't forget the amount of line will increase with each rotation as the circumference is increasing as the line builds up

What a palava 🤪I'm thinking I'll measure 1m of the backing see how many turns of the handle it takes then times that by 180, that should be there or thereabouts ...I hope

For the poor schmucks amongst us who dont have a bundle of spare spools you can easily do a similar thing, but it's a bit long winded to explain...
Add your new line onto your spool, add a piece of tape to finish off, then top up with your spool with your backing.
Now use a drill to spin off the backing onto an empty bulk spool. Then remove the new mainline onto another empty bulk spool. Now put the backing onto the reel spool. Add a wrap of insulation tape around the middle. Now transfer the new mainline from the spare bulk spool onto the reel spool over the backing, and its done.

It is simpler to wind all the main line onto an empty spool, then fill the spool up to the lip with backing. Next wind this all onto a spare empty spool, then reverse wind it back onto the reel.

Quick question as I have a similar quandary - how are you going to measure the back line going on?

Grok (Which is Elon Musk's / Twitter AI) is correct.

I worked it out at as 181.24m @ 0.35mm

I have an empty spod reel spool which has a 300m capacity for 0.35 mono
I have 275m of 0.23 braid to load, I have some cheap mono to use as backing, how much backing do I need ? Backing mono is 0.35

Thank you
