I have gone to the ridiculous with a 1 weight before......I cast a 2/0 Hollowfleye with the wind to stripers feeding at the base of a bulkhead......landed several stripers up to 18lbs that day. These were short casts (if you can call it a cast...kinda more like launching it up in the air and letting the wind take it out 30-45') to active fish and was a hoot!

With that idea in mind I have accidently broken a 1oz rod while fishing the salt by forgetting it was a 4wt and waterhauling it (just can't waterhaul a 4wt like a 12wt) ......broke 4" above the grip.
