If yours was not a rhetorical question then let me attempt an answer. As a fellow Texan I regularly fish a 00 wt TXL, 1 wt Orvis, 2 wt Scott, and 3 wt Sage LL, and love them all.
As you can see from the photo a nice 3lb bass did *not* overly stress a 00 wt TXL. If you think about it for a moment you may realize that the weak point in your tackle is usually the tippet and not the rod. As long as the breaking point of your tippet is lower than the breaking point of your rod you're okay and a lighter weight rod can cushion a 5X tippet as well or better than a heavier rod.
The downside to a 00 (or 000) wt is the size of the fly you can cast. If you're fishing for bass this can be a big hurdle but if you're fishing for trout or bream then it's usually not a problem. High winds can also be a problem.
The upside is that they're an absolute pleasure to cast, can place a fly very lightly, make medium to smallish fish even more fun, and they're light weight so you can swing one all day without wearing yourself out.
The bass below was taken on a size 14 hair hackle dry and landed in less than 2 minutes. But please, don't take my word for it--find someone who has actually *fished* one of these rods and talk to them or better yet--have them take you out to try it. Listening to a bunch of guys who have never fished one--regardless of how long they've been fishing--is not the way to learn the capabilities of any rod.
As for price--who can justify the price of *any* premium flyrod? And why try? This isn't a serious endeavor regardless of what you might read. Other than having a good time is there really any point to what we're doing here?
Best regards,
Jerry
BTW, these rods are a blast with big chunky bream too!
