It looks like that outfit doesn't come in a 7-wt right now. You could probably find a similarly priced outfit at Bass Pro/Cabela's in a 7wt or, if you're like me, buy the 9ft 6wt today before you change your mind. Paralysis by analysis, so to speak. All points above are valid, but that Orvis kit will be ready to go out-of-the-box, just add flies. I'm sure there are local fly shops to get some to start and you could be on the water by Tuesday. You could even get some poppers are Walmart and be ready to go.
