I don't know how my name got dragged into this, I've been asleep all day (nightshift).
Firstly, here are my observations on some of your points.
"Tim Birch, your comments "I think therefore they may patrol the edges of the baited pach until the smaller fish dwindle?"
Stu - It's not they they will dwindle, its that the bigger fish will bully them out.
Frothy - could it also be theres little bait left to hold the smaller "hungrier" fish so they move off and the bigger fish move in to polish off whats left?"
Riks comment - Smaller, hungrier fish, still hungry, then move away from the baited area, because there isn't a pile of bait left, only a small amount, which the bigger fish will find appealing?
Now that is a crock of shit.
Why would the smaller fish move away when there is some bait left?
Why would a bigger fish not get in on the action?
If it's Stafford Moor, then the fish are hardly older and wiser.
Maybe, they would hang outside the general melee, but then baiting a wider area would probably be preferable anyway, but then they would only wait around so long and then they get in there themselves.
I've seen carp nudge other carp out of the way and it's not necessarily the bigger fish that bully, but they will move in on the feeding activity.
Apart from physical bait size, then no bait can be specifically aimed at bigger carp.
It doesn't work like that.
Application yes, but I'd be more inclined to feed heavily and continually, to draw into the area and catch as many fish as possible.
Experience (mine) states that the bigger fish WILL commandeer the area.
Stuart raises a valid pointer in trying different methods on different rods as you may be unaware of a method that may have absolutely slayed the place last year and the fish may be very wary off.
But Frotheys general statement that big carp are not where there is any bait sounds completely off the mark.
Why would this be?
Do carp grow big by not eating?
They may be wary of beds of bait, but if there are large numbers of smaller carp, then they'd better get their heads down quick, or else the large carp will quickly become skinny carp.
I mostly agree with the points that Stuart has raised and the advice he's given, not because he's a mate, but we fish together because we tend to have the same views.
I'm not going to fish with somebody who doesn't have a clue how it all works and only fishes waters that have no relation to anything that I'm targetting.
