let'g go! 6kg on a fly would be quite a fight...not as big as some of them in the Seychelles but big enough!

If you can see them and cast up current, floating the fly (dead drift) past them in their "feeding lane" you might have a chance. I don't think you would have much of a chance if you were just blind casting to them...need to be sight casting

Budi (snookfly) mentioned they can be near sangyang but the one time we went out there together we did not find any....maybe we didn't look in the right spot.
