p-line cxx is some really strong stuff, but its pricey -- its double the cost of tri +
Izorline is a decent line, i see a lot of guys using it out west for salmon fishing. i don't think i could bring myself to use it in the surf though -- i've had issues with its abrasion resistance.
maxima line is a really nice line and i think that once i run of out tri+ it will be my line of choice. never seen it in any tackle shops along the east coast. the stuff is made in germany and can be ordered from cabelas. its a west coast standard -- i think a 1lb spool of it will run close to 90 bucks

the only problem i have with the line is the price and the hi-vis color is a fiberglow pink.
