Tim:
I hear you 4 x 4. But man I envy you. Quality trout fishing -- it's like you step through a door into another world. Don't get me wrong -- I love tossing the suds for stripers -- but, at least in my experience, no fish has ever made me think so hard to catch it as a trout. RE tackle: you don't need to spend major bucks for a decent trout outfit. Sertainly you don't need to worry about stuff like backing and bar stock reels. A $60 rod and a $40 reel will cut the mustard. Best of luck in HI: bet you'll have fun!
