Find out where John Kents flies are sold, he makes killer chronomids. Either that or if you can tie them yourself, check out some of Brian Chans flies.....he may sell them on his website. Have a great trip!
Start off with chromies, black and red snowcones, some bloodworms, some green ASB's all in sizes 12, 14, & 16 on long shank and scud hooks with black and white beads. That selection should get you going, but you never have enough flies.
