I tie on a Griffin Montana Mongoose which I got at a deep discount and also on a Renzetti Traveler. Both are really well made. The Griffin has lots of features for the money and so does the Spider which I've tied on and enjoyed using. The only drawback for me is that the jaws on the Griffin are a bit cludgy for really small flies (small midges). But Griffin makes a good product that for me has been 100% reliable.
