I remember when 60ml of Shire Malt would do me for a month.....now if the same lasts 4 days it's a miracle.
Saying that though, I must be the only ape around who uses less at 3mg than I do at 6. I just find that i pick up the mod less when dripping than when using a tank. Must be down to the satisfaction of blowing a huge cloud and then waiting for the fog to clear before blowing the next, I spose.
