Electronicstix.com has factory laser drilled boges. Sorry for no link but I'm using my phone now. I prefer them over the ikenvape platinum for the ONLY reason is I personally like the 2.0-2.2 resistance of a LR boge as compared to the 2.8-30 ohm resistance of the ikenvape platinum. Don't get me wrong. I've got about 50 35mm ikenvape platinums that are diffenantly going to be used. It will take quit a while to use up all the cartos I have stock piled. The LR boges on my unkicked SB gives me the wattage range I find is my sweet spot. Hope this explains some of my reasons for likening the LR boges. May be a silly reason but any one that knows me already knows I sometimes get stuck on certain products. Guess its the OCD kicking in. Again.
