I also use ultra green as a tippet. I also construct my entire leader with Maxima. There is a chart that was developed by Bill McMillan to size your leader to maximize the leaders ability to turn over when casting. I don't have the resource but I'll see if I can find one to post. Maxima Cameleon is stiffer for butt section and I use Ultra green for the tippet. The abrasion resistance and knot strength is why I use it.
