Nicely done Bubbleboy, nice outfit and much fun to come...
Gosen 8 weave. I believe the PE2 Rating (20-30lb or so) fills a 5000 reel size perfectly. I have it on my Sustain and it's brilliant with a Shimano 5000 size reel and that specific rod.
The PE rating has become the Japanese standard of measuring braid, as it measures line diameter and not breaking strain. It's easier therefore to figure out what to buy to fill a certain spool size. You'll get the idea from the link below.
http://oceanbluefishing.com.au/2010/06/24/pe-rating-fishing-line-diameter-chart/Different braids with the same line diameter may therefore have different breaking strains depending on the quality of materials and the weave.
So first pick the PE rating that will fill a 5000 spool, and then you can look at the different products. The stronger the breaking strain the better the product obviously.
Go for an 8 weave as it is far smoother than the cheaper 4 weave and is better for casting, whereas a 4 is OK for a backing line or for a cheaper jigging option.
The 8 weave Gosen is absolutely perfect and has a very good breaking strain and is unbelievably smooth, but I have been told the JDB is also decent and it's about 20% cheaper.
Do the right thing....
