Just reckon the pellets buying from my mate is from Skrettings (5pounds for 5kilos!, they are all good and catch me fish. We used same feeder tactics with hair rig paste (2pound per kilo!!!)He caught 15 tench in 6 hrs, I caught 15tench in 7hrs, another time 19 in 8 hours. The tench averaged 4lb to 6lb12oz the pellets and paste can't be bad. I wonder those pellets or pastes cost 3pound for 500g will caught me more fish?
At the end of the day, pellets are pellets, paste are paste there's no magic! They varies from oil content, colour, decomposing rate, sinking rate just different properties there's no secret ingredients, just different situation needs different pellets that's it.
