Re: what 6 weight for smallies
Just some rehash of what I said in the past about short vs long rods for bass.
If you plan on making shorter casts (those within 45 feet or so) with a floating line, it's hard to beat the short rod.
If you plan on casting a variety of distances with a variety of line types, you should err towards the long rod.
With that out of the way, I cannot comment about the St. Croix rod.
Here are a few rods that you ought to cast:
Premium (over $600)
Mid Price Point
Lower Price Point (Under $300)
There are other good rods out on the market. Others will mention them.
