I agree, a rig like yours or the Ted's with a couple of 5/8 bands will provide you with all the crap-fish you'll ever develop a taste for.
Give yourself the edge and use a 3/8 shaft. The added strength/weight of the shaft will punch through the scales and often right into the log just behind it.
Oh, and I reiterate my favorite recipe for carp, me being a Swede and we Swede's eat fish 4 times a day... (easy there Ted...)
Take a carp, no matter what the size. Go to a hole you've dug next to a rose bush. Drop the carp in the hole and cover with the dirt you removed earlier. Tamp the pile with the shovel and walk merrily away. Mmm.
