You have to determine for yourself what type rod you prefer. Some like fast rods, some like the slow rods.
Like Ray, I'm also not thrilled with the sub 7' rods for anything. I had a 6'6" rod and considered it more of a toy than an actual, functional flyrod. I prefer longer rods as IMHO they are much more useful for a broader range of conditions. I also prefer a 4 or 6 piece rod for transportability and ease of breakdown and carrying rigged (with reel attached) in a carrier which is hard to do with an odd-numbered piece rod (like a 3 or 5 piece).
My local rod is a 7'9" 3 weight, 2 piece. I don't travel with it so number of pieces isn't a concern here, although if this blank was made in a 4 piece, I'd definitely switch and build one up, as again, I like the portability of the 4/6 piece rods.
You've received good input, but you need to define your price point. The Sage SLT/ZXL series are pricey. So is the TXL in 000-3 weight. Great rods but do you want to spend that much? Also the TXL is a 3 piece, which for me is not an optimal configuration. The SLT can be had in 4 piece which is a plus. You can find rods by other makers though that would meet your criteria--ie TFO Finesse, 7'9" 4 piece 3 weight, Cabelas Stowaway 6 piece in a 3 weight, plus a plethora of other rods.
Here's one you may want to consider. I don't own one but it sure looks like a nice, cheaper sage rod:
