Morning Doc,
I dont see how you could go wrong with any of the first 3 (you can see my experience and subsequent explanations on TFO here (

I fish mostly small streams in northern/central Calif and have found that something in the neighborhood of 7 works out the best for me, 6 is just to short if I find an open run and 86 is too long for brush hoping. I currently own 3 Sages and can say that they are sweet rods
Sage Fli 76 (4wt)
Sage 470-3 TXL
Sage 490-4 Launch
I have never had the good fortune to own or even fish for any length of time with a G Loomis Metolius but everything I have read says, like all G Loomis rods, that they are awesome..
Post back some feedback on whichever you end up getting as I am considering getting a 3 or 2wt (probably a 3, not sure I spend enough time on the water to be able to handle a good fish on a 2
