Hi Ian
I've been out here (south china sea) nearly 3 months now
I brought a couple of 9wt outfits with me to go offshore looking for GT's, Tuna, barracuda, spanish mackeral and the like.
I would say i could do with a 6wt (i brought my 5 with me too) for fishing the coastline, some of the flies a fairly smallish. Not like the big things i need for the offshore.
Depends what you have in mind.
As for lines, i spoke to lots of people (especially in OZ) before i came and the concensus was that Rio make the best tropical spec lines.
Lots of models and sizes (sportfish and guide fishing stockists)
I have Rio Outbound short head tropical floater and Rio saltwater Tropical Intermediate lines and they are fantastic, the intermediate is a real missile and flies for miles.
The short head is great for big poppers. They felt very stiff at home (still castable though) but here they are lovely. Smooth yet still firm, great to cast.
My standard lines from home are too soft here, most of the time (ok in the middle of the night
) You can cast them ok but when you start to use weighted flies they just die.
Where in Malaysia are you going (we are 45mins from Miri where there is some great fishing, mostly offshore or inshore)
I know there is good fishing on the peninsula too, depends what you want to catch. As i said i'm trying mainly for GT's, gives me a focus plenty different from the norm at home.
You will need a 9wt at least for this, bring a 12wt too and there is lots of Billfish to catch (klingons are the fly
) Check out the saltwater guys at Sexyloops Board, many know the good fishing here and around Oz and are well worth speaking too, some good stuff on there at the moment about Malaysian Billfish
Hope it helps
Cheers
