Chris Dore will be able to help you, but from personal experience (I'm a fly fisherman 99.9%) I take a pack spin rod armed with a Rapala CD5 everywhere I fish for fun and stubborn fish or fish in large featureless pools / pools that cannot be fly fished due to overhanging foliage and generally in high pressure area's like where you are heading, ultra-light spin gear can/and usually is absolutely deadly over fly in my opinion and usually results in the largest fish, if in a pool holding more than one.

I only use CD5 and CD7 in Brown Trout pattern - nothing else compares IMO! if you buy from overseas, they are around $9 landed compared to $25 locally! Brown's seem to particulary like their own kind... the duller patterns are great, just stay away from the brighter patterns.

Cheers for the replies guys
