I own a 9.5 ft' 6wt BIIx Winston with a fighting butt.
Can't answer your question directly but I have completly satified with the purchase. Purchased from Front Range Anglers- it was on sale,with no tax or shipping costs. That said, it was expensive but at least $100 cheaper than every other place I looked.
Works great for bigger rivers. I also have dry fly fished with it on medium sized streams. If it works for you and you have confidence with it and the money- go for it.
