JWB,
that is the same set up I made, I would recommend you put some mono on the reel first. forgot how much I put on mine, maybe 10-20 yards of 10 pound XL. this will grip the metal spool good. if you tied the leadcore to the to the metal spool the line could spin around on the spool with no spool friction and you would be useless and in trouble. when you tie the mono to the leadcore, peel back the line covering from the lead about 3 inches and cut off just the lead, pull on the covering, and it will give you a much smaller diameter inwhich to tie your knot. with 10 yards of backing you should be able to put just about all 10 colors on the reel. you could not do that with the model 27. hope that helps. Jack..
