I need more draw i read somewhere else about a new 901 pen style that has 4 holes is this the most? Where can i get one? I'm using a TW super 10cm which I don't know what else it is called and its okay but i would love a better draw i.e. easier i have to pull hard on this one to get the light to come on so my question is which one has the most holes and easiest draw. Sorry for the winded question..
