I've see folks use those rigs but it just looks like a lost rod waiting to happen. You get a 30#-40# bruiser carp on the end and those reel "stops" don't look like they would hold.
I use a length of 550 cord tied to the reel base with a loop on the end I place around a stick I drive down into the bank at a rearward angle....It has saved me many a "tragic bank accident" for both carp and big cats.
We always used a PVC pipe cut at a sharp angle and driven in the ground.
It's also great for surf fishing.
