i was robbed a few weeks ago, and once the insurance money come back, i'm thinking pretty seriously about buying fly tackle instead of replacing all of my spinning stuff. from the little bit i have heard and read about, temple fork is a pretty good way to go for quality/price. anyone agree or disagree? as for what i want to do...i plan on doing a little redfish/speckled trout fishing in the bays, and also throwing small shrimp paterns to dock lights from seawalls at night. but i'll probably do more beach/jetty fishing. there i might catch spanish, big trout, reds anywhere from 15" to 35", an occasional shot at a king or tarpon. i was thinking about an 8 weight so i wouldn't be overkilling the inshore species, and with spectra backing i think i can stop a king or small tarpon. am i way off in assuming this? what if i stepped it up to a 10wt? would that be overkill for fishing the flats for trout/reds? i realize the best idea would probably be to get 2 different set ups to do 2 different things, but that might get a little expensive.

so, i'm just looking for a little advice, you guys see the species i'll be targetting from seawalls, boats, wading, and probably a lot of time at the jetty fishing for macks. what are your opinions on what i need to get started. also, should i lookt a sinking or floating fly line, and what are your preferences for leader material? i'm brand new at this, so anything you think i might need to know, go ahead and tell me about it!
