I must say, I'm a bit wary about the braid. Not just the locals but, worried about burning my finger up. Lol
Guess I have to learn sometime.
With a mono shock leader, you'll only be touching the mono during casting and during the fishy unhooking, so no pressing need for finger protection or a casting cannon on yer spinner ... and a hefty 50# mono shocker will be quite kind to yer trigger finger.

hate braid for revolvers, but I'd consider it almost mandatory if yer hunting the usual game fish off the beach with spinners. There's security in knowing you've got a deep spool when you hook a big one, and you probably will eventually. And due to the thinner main line, your casting distance will increase to boot, which is always a good thing.
30# braid will be in the .011" diameter range as opposed to .014" for Sakuma 18# copolymer. Your Slammer 5500 with load about 230 yards of typical .015" 15# mono, whereas you will get over 400 yards of .011" 30# braid. I'd load at least 300 meters (325 yards) of 30# braid and another 30-40 feet of 50# mono for the shocker. Yer pretty much ready for whatever ya hook up to. FWIW, quality braid typically is underrated and will break at a higher tensile strength.
