You have obviously given this alot of thought, as well you should...this will be a super sweet small stream rod and reel outfit! Your reel will most likely always weigh more than the blank weight since you will add backing and line in addition to the weight of the reel itself.
We don't currently have the 3 weight Boron II in stock, but we will be happy to get it in. That way, we can take your reel choices and be able to tell you which one feels the best with it. Any of the reels you have mentioned would be good matches with the Winston. We would be happy to help you further. Just give me a call...our toll free number is 877/448-3474.
