Yellowlab,
I have two friends who love the St.Croix 14 ft 9/10, which they have bothj owned for 5 years now. One fishes it with a 9/10/11 Windcutter (he likes a slower rod) and the other fishes his with the 8/9 Mid Spey (he likes a longer belly line).
The Redington is somewhat faster (not really fast, more like a fast, medium rod) than the St.Croix at a similar price. Take you pick. Sounds like you like medium-fast single-hand rod, so either of these would be to your liking.
The Sage VPS 9140 is just like the old brown 9140. And it is considerably cheaper than the new 9140, which I assume is the one you casted. It is a slow rod; however, it is not that much slower than the new 9140. Although the old brown 9140 was my first 2-hander, I quickly got tired of its slowness.
I owuld opt for two 2-handers, one for summer in a lighter line like the either the 13 footers by Redington and St.Croix, and the other a heavier line rod like the 15 footers from either of them. This way you will have a rod that is more suited to the water and flies you will be using at different times of the year.
