It is no surprise that 10mm mini-boilies have accounted for some of the biggest roach in recent times. These relatively large, hard baits are very selective for specimen roach, as smaller fish simply can’t fit them in their mouths. Scopex Squid and Tigernut-flavoured baits have both worked well for me.
It isn’t just carp venues where the roach fall for mini-boilies. I caught my biggest roach from Lochnaw in Scotland on a boilie, simply because it enabled me to single out the larger fish from among the millions of tiddlers that pounced on more traditional roach baits instantly.
