I have got the ross flystart on my 4wt. It works fine. I have had no problems with it. It was good for the money since I spent all I had to spend (not much) on the rod. I figured in my case the reel was only there to hold the line out of the way.
Looking back though I might have gone for the orvis or a slightly used orvis if the price were right. This is not based upon anything but the desire for the road not taken
