Hi Damien,
The Saragosa is a rare beast!
There are very few reels under $1000 I have seen that have the gears & drag pressure to tolerate GT fishing.
For a rod, either the Shimano GT special, Daiwa Muramura or some of the Daiwa Monster Mesh rods, if in stock, can still be great value and as an outfit, would be around $1000.
Casting weights would be more like 90-140grm to get the best out of these rods.
For braid, just for durabilty I'd go to Sunline Super PE in 80lb as a starter, though, just as there are more refined rods and reels, so too can the braid be nicer, such as Daiwa Sensor or GT Avani....it comes down to a whole package I guess.
I go for something in the PE 8-10 since most places I like to fish the GT's are cranky, large and live in horrble structure....
One thing is for sure. When starting out chasing GT's the learning curve is very steep indeed!
Aaron.
