A couple years ago, I spotted a good deal on a 9' 4wt Classic Trout, so I bought it for my wife. After casting my 9'4 wt Helios 2 for a month, I took her out one afternoon with her Classic Trout. I thought it compared very favorably with my H2 except the CT felt very HEAVY. After seeing this discussion, I pulled them both out and weighed the two middle plus tip sections.
Helios @ 339 grains
vs
CT @ 448 grains.
That 32% difference wouldn't bother anyone who isn't already accustomed to a lighter rod.
