One of my pet peeves is anglers using rods far too heavy for a water... I was on a small clubbie a wee while ago, and a lad was using a pair of 3.5lb rods and big pit reels on a small water with fish of less than 30lbs... probably using 15-18lb line where you can quite happily land a 20 on a light 1.5lb/1.75lb rod and 8-10lb line... balanced tackle is far better than overgunned rods... I appreciate that it may have been that he can only afford one set of rods, but I think a chunk of the blame has to be laid at the feet of the media for advocating heavy gear on their videos, and not making a point in telling folks the heavy gear isn't required for a large majority of UK carping.
Unforgiving, heavy poundage rods are just not required and in the hands of the inexperienced can and will cause mouth damage, especially in conjunction with a tight clutch...
