Re: Moving from Chicago to Houston, Help!!!!
Howdy here in Houston, first thing is we fly fish all year long.
I'd start with the 8wt and wait on the 10wt. The fish most of us target are Redfish and Trout (spec's, spotted weakfish). Snook do exist but not common even where fairly plentiful. We get tarpon but that can really be based on weather conditions. Wind is always an issue here so bit faster rod, sparser flies and SW tapers rule the day.
If you want "bullet-proof" the TFO's warranty is the choice as they warehouse out of Dallas and replace/fix and problem for $25-30. We shipped then one on Monday and it was back by Thursday. Reels just need constant maintenance for our hyper-saline bay system. Buy a can of CorrosionX and carefully clean and wipe down after each day on the salt.
Join Texas Flyfishers as they are very helpful. Houston has a really great fly shops, IFly near Galleria is a great shop with no "soup Nazis" working there. FTU (Fishing Tackle Unlimited) has 2 good shops on west and south. Both understand saltwater flyfishing.
Joint Texas Flyfisher as they have lots of folks to fish with.
