Speargun Rigging Lines

[PigStikr]

Dusting off my homebrew 60" and have a couple questions, not remembering exactly the line sizes after 6 years in storage:
The gunline is connected to the floatline is shock-protected with 1/4 black rubber tube stretched over the gunline knots and tied with a very thin white braided stuff. The wishbones are inserted into the 5/8" bands tied with maybe a 1/32" white 3-strand that has some kind of waxy coating. The gunline is a 1/16" maybe purple spectra?
Also, the wishbones are two types, AB biller ones that are ground thin in the middle, and normal ones that don't need to go into biller notches. The biller ones tend to break at that thin section. I could go with more round wishbones (source?) or maybe, if i recall, there is a way to just use braid with knots?
So any ideas what each line is made of? Where to get the wishbones?
Any and all info appreciated.
