Juro, I agree. If your feet hurt, you can't see fish, your pack doesn't feel right or you look for something and its not there you are not going to have as much success or fun out there.
I have used a lot of different rods and reels and have caught fish and had fun with all of them. Last few trips when wading I have used a Gary Borger Pro Series 8 wt with a Sage 2580 reel. Both are light weight and the rod is easy to cast. I have started using the Rio Redfish line when wading. Loads quickly and is good for anything within 60' which is usually all you need wading.
