I stopped using oiled pellets ages ago... I use coarse pellets as they break down quickly... That said, I've often found that pellets tend to make carp pre-occupied with them... especially micros and flavoured ones more so... I used softened 2mm and Goo-ed pellet in bags, the fish were tearing up the bottom to get every morsel of 2mm pellet, yet ignored the hookbaits... now I use a matching hookbait and pellet glug and I get better results
