I bet that was a blast.
I use my 6wt. Z for everything now, I picked it up just for fishing smallie originally, then it just started to take off from there the species I went after. I have went after bonefish with it and landed one that was about 5lbs, have landed around 50 carp on it,one was about 35lbs this summer, hundreds of smallies, a nice summer run steelhead, two flathead around the size pictured above,and tons of trout.
You would be amazed the pressure that you can put on a fish with a light rod, its all about the angles. That big carp above only took about 5 minutes to land. I wish I would have took a pic of the carp I landed on the 4wt. my body thought I was crazy for going after the fish with that, but you have to have fun every now and then.
