I would add to this thread that while I do not believe in such a thing as a big fish rig, in my opinion you will increase your average size of capture by using pop ups. The higher you fish them off the deck, the higher your average size will climb. If you whack a pop up 3 inches off the deck you'll hook fewer small carp imo as it just looks alien to them. Bigguns wont be be able to tell as they are approaching from above due to their sheer size.....
I have a close mate that's fished the same waters as me for the last 5 years. His average, every year, has been significantly smaller than mine, and he catches just as many fish. Only difference is he fishes bottom baits where I use pop ups. Coincidence? Maybe. Maybe not.....
Last year, in an attempt to target that huge mirror I has in October, I increased the height of my pop up rigs significantly to avoid the smaller fish. I landed 16 fish after that modification with an average of 31 lb, and then the biggun at 49. Normal average on this water is about 25 lb, my smallest fish was 25 lb. Coincidence? Maybe. Maybe not.....
You might have to wait longer for bites with big blatant pop ups but when the bite comes I find it's worth the wait. My first piece of advice to anyone looking to target big fish would be to use blatant pop up rigs.
Seems to have worked for Vik too looking at his results last year.
