I have found these 8.5mm pellets very suprising that have worked when nothing seems to be biting.
Excellent products. Great for canal fishing for roach and and hybrids.
C-Food Pop-Ups are available in either 12mm &15mm or Dumbell Wafter. Designed to complement the C-Food Boilies these super buoyant pop ups will leak off attraction and get you more bites.
