Yes, but more when I've put a carpet of bait out, very few on just stringers, bags or individual baits.
Add to that, put out boilies with a throwing stick, you don't tend to create enough attraction for them to feed on the spot, the distance between each bait is not always enough to hold them. Put those same baits in with a Spomb and it can be as the baits tend to be closer together.
On Alton Water, if you avoided bream patrol routes, you could put out big beds of groundbait and catch only carp. The closed ends of bays weren't areas they were comfortable going in to, whether it was too close to the bank or too shallow I'm not sure, but I've caught very few bream at ranges less than 5 rod lengths from the bank, yet carp come in very close.
Put very little bait in and they don't usually feed on the spot, there isn't enough to hold them to feed, unless you happen to bait up over a natural food area, like a bloodworm bed.
Chilli flakes and crushed chilli sauce also have an advantage in that swans are often reluctant to feed on spicy particles and groundbait.
