What Dacron for Penn Plastic Spools?

[Beachmaster]

I have a few vintage Penn reels with plastic spools.  I understand that it might be a good idea to spool a few yards of dacron on the spool first then fill the rest with the mono of my choosing.  What size dacron and yardage should I use?  My Jigmaster, 155, and 77 all have plastic spools.  Thanks!

I would use 50# and fill the spool at least half way.

Dumb question.  Do you spool Dacron on just like you do Mono?

[Keta]

I do.  Most of my reels have at least 1 layer of dacron under the Spectra.

I was wondering also, but instead of Dacron, can you substitute braid as a replacement for Dacron. Should have the same characteristics and be suitable for plastic spools.

Yes, Spectra compresses less than Dacron and it works as well or better.  I would still fill the spool 1/2 way.
