Just had to post this as i've had some extraordinary results on these during this freezing winter.
I've been baiting up an area of my local syndicate with about 500g of 10mm boilies all autumn (twice a week) in a large 5m x 5m square at about 30 yards range.
I had caught 6 carp in October and November (which is good for the lake) going up to 29lb, but in the weekend just gone, i had 7 in a 24hr session. (between 16lb & 25lb)
I've been looking for a winter bait for about 5 years, and i think this is the one! The boilies are the same colour as the normal tigernut boilies and give off a lovely chocalately smell (like cocoa powder) and i'd defo reccomend them to anyone for the winter months.
