A 5wt is definitly do able, but you need to be really carefull with it. once you get a big boy on there you will want more then that. I caught my biggest carp yet on a 5wt and it was terrifying. Ending being close to 16 pounds. Never again. I bought an 8 wt that week and havent looked back. The konic will be a fine reel for them, I have landed them on konics, sages and cabelas cheapo brands.
I always fish for them wading since thats where I see most of them but if Im out on the boat then hey why not??
