I have caught and landed carp that are 30" plus on my 3 wt and with 6X tippet material. Don't be in a hurry and try to horse them with light tippet. That 3 wt will throw number 6 hooks wrapped with lead and a tungsten bead with no problems. Maybe can't throw 9" muskie flies, but go have fun because fun is what is in front of you. Enjoy and you probably won't use a 6 wt again unless you want to chase steelhead or something very big indeed.
