I think you have gotten great advice above. I am not an experienced bonefisherman but was in T&C with my family last March, found a great guide, caught some nice fish, and caught a few on my own as well. Happy to tell you what I know (though it may only fill a thimble). Send me your questions or send me a private email. I'd be happy to talk live time if that helps. As to some questions you've asked, I used a 10' 7 wt Sage SP (so your 8 wt should be enough) and yes, you need a license to fish both with a guide and on your own. Do be careful of the protected waters off Grace Bay - can't fish them from shore.
