I'd go for 30lb Fireline for drifting and any situations where there's a risk the line will come into contact with snags. It's slightly thicker but indestructible and easy to knot up. A lot of people also use this line for lure fishing.
I like Whiplash, the low dia braid for laying on, float fishing, trotting etc. The 30lb is same dia as 6lb mono but you have to be a bit careful knotting it, sliding rig stops upand down it etc.
When you stick it on make sure it's wound on under a decent tension. This avoids the tangles you get with new braid when coils of slack line fly up the rings.
You also need to watch you don't let a couple of coils of slack on - like when you turn the reel handle to close the bail arm after you cast etc.
Dipping the spool in the water before the first cast also helps.
You can get cheap braids from Sea Fishing mag - Fireline's around ?14 for 100 yds, ?24.99 odd for 300.
It's worth up-rating your trace wire to 28 or 30lb when you use it. Using braid puts a lot more strain on knots, swivels, crimps etc so it's better to err on the safe side.
