frozen boilies all the way for me,always been more productive using them, the only prob is they go out of fashion as it were,bait companys will not stop until they deem to have found the ultimate bait,it aint gonna happen,different waters different tactics,bait etc,i regularly stick with the old favourites,smokey mackerel and tiger nut boilies always seem to produce on heavily fished waters where the rest of the lake are using the newly released bait of the future lol
just to add,you can only defrost and refreeze them three or four times so keep them all frozen and just take what you need ea
