My dripping atties of choice are LR901 with a drip shield (an LR 901 - 1.5 or 1.7ohm gives the very best balance of hit, heat and flavour of any regular price atty IMHO) and LR306 (normally at 1.5ohm). Of the 306 atties 've tried, I still prefer the Ciscos - the Olympics are noisy and the io6s don't last as long as the Ciscos for me... The HH.357 901/306 hybrid is a great driping atty as well (but more expensive)
