I’ve been thinking about this bait splitting issue while rolling my own baits this morning, as a thought, have you tried rolling the paste around an existing “normal” sized bottom bait boilie to make them the size you want then boil them for 20-30secs (might need to play with this a bit) to just skin the paste? I’ve just made a batch of boilies, I made the mix too dry and it was a [censored] to roll! The addition of robin red and the use of fos-oil (as opposed to my usual salmon oil) seems to have made the mix greasier which doesn’t help! The fos-oil is a new addition, so I’ll switch back to salmon oil next time as I don’t get these issues.
