I have a 6 wt Predator. I throw a SA 7/8 wt bass taper line on it and can throw meaty rabbit strip streamers with ease. I love the rod. I did break it while casting on my first trip with it, but it was pretty late at night/early in the morning on a gravel bar on an overnighter so I will just say it was my fault. BUT, they didn't charge me to replace the broken section and upgraded my rod tube that had a broken zipper also. Their customer service is tops.
I also have a 9wt Crosswater outfit. My only gripe with it is the Rio Mainstream line that comes with it.
