Chris,
I use YGK UltraJigMan PE#3 47lb and really like it. It is really thin which I like. I'm certain that any other quality 8 ply braid in the same size from the major brands would be great too. From what I've heard alot of them are the same with only different branding......
Note that I haven't many other brands so it is a reasonably biased view. I chose this one as I found it was good value for money.
Cheers,
Simon
