in the winter mainline pine apple pop ups all the way.
but for all round use either nash white chocolate pop ups or richworth tutti fruitti or kg1 definately
theres is nothing wrong with having more than one bud. mine would be banana tuttis then squid and octopus. i would say always have more than one fav as then you feel its going to get you a fish..but if you stick something on that you dont like then its not going to feel right when its out in the water well i do any way
thats a tricky one, theres so many id have total faith in, nashys scopex squid or white choc for example tend to work everywhere ive found. but if i had to use one type for the rest of my angling life id say probably the trusty rod hutchinson mulberry florentine. having said that im doing ok on mularkey pop ups atm.
