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.
Nut 365 Pop Ups are available in either 12mm &15mm or Dumbell Wafter. Designed to complement the Nut 365 Boilies these super buoyant pop ups will leak off attraction and get you more bites.
