I used to find more drippage (?) when I used a wand on the end of a polythene tube; now I attach the wand direct to the tap on my bottling bucket and offer the bottles up to the wand (as opposed to dropping the wand tube into each bottle) I get less drips.
What I do find, though, which is a bit of a pain, is that the response of the wand is non linear as you press the spring loaded tip down to the bottom of the bottle; if I press it right down the flow shuts off - I have to put the wand down to just touching the base of the bottle and then a few mm further to get the optimum flow. Push the wand too far and the flow decreases. Is this just me and my wand? (One from Wilko, one from my LHBS (sadly no longer in business) ).
