I'm planning a trip to MT this spring and my research has revealed I need a new fly rod thumbs

I'm looking for a 6wt, 9' rod that can sling streamers and leeches on the big MT rivers in the wind. Once home it will become my main estuary rod, typically HC SRC's. I'd like to keep the price below $300.

So far I plan on fondling the following three rods:

Sage FLI 690-2
Orvis TLS 906-2 &
Powell TiMax 906-4

Anybody have any experiance with these rods?
Is there another rod I should be looking at?
What are others favorite estuary fly rods?

Thanks and tightlines!
