I have been using a Drennan insert waggler tip as a float(rather than use a swan vesta like Rob),on Thursday afternoon I popped down the river and fished a swim where this tip wasn't bouyant enough,I looked through my box and found a tip from a Drennan big bodied loaded waggler that had a bulbous(almost windbeater like)crystal insert,which worked perfectly,taking 3 no.4's and 2 no.8's,on my last cast(my second one,lol)I hooked a chublet about a pound which leapt clear of the water and into a big clump of rushes,this lead to me cutting through the silicon float adaptor and losing said tip,here is the crux,Drennan sell packs of tips,the ones I want,in packs of 6,3 straight tips,3 bulbous ones of differing lengths for around £3,problem being,nobody has any in stock,ive looked online on many tackle shops,fleabay plus others,nothing,why,a shortage of postmen perhaps....
