If you are undaunted by the prospect of cramming that much wicking material into the 1.2 shell...

Once again thank you for the info.
I find that building a vertical coil I always add the wicking material to the coil before inserting in to the cup and it does need quite a bit of cotton so it is a snug fit.
As long as I can get the top off to give me plenty of room to insert the wicked coil I might get some to give it a go.
Cheers all
