The best bit of advice I can give you is pop down your best local tackle dealer and go and pick a few up and get a feel for the rod, we have had several budget rod threads and all usually throw up a multitude of different answers and people have found one recommendation better than the other because it feels better for them
Personally I can recommend both the Fox Warriors and Sonik Blacks as good budget rods, others have found the Shimano Tribals excellent value.
With regards to test curve I will leave it for the lads that fish the method feeder on a more regular basis, but im guessing that it will depend heavily on the sixe of feeders you intend to use
