Any one of those rods would do,go with what you can afford and what feels right.Last week i took a 6110 z axis for a spin with a sink tip line,a little heavy for my taste the sink tip was too long but had no problem casting clousers to the other bank.I also have a real cheap 6wt that i use now and then for casting heavy rigs and it works just fine too.So cast a few see what feels right.
