Can you modify several A6 rda's into bottom feed. I'm down to my last RM3 from ReoMods. They no longer carry the RM2 or RM3. I prefer the small chamber, luckily I purchased a cyclone from you in 2015. Avid Vapor has the A6 @ $16.99, High Desert Vapes @$14.99. Would it be easier if you just placed the order? Would you have any bottom feed center pins that would fit the A6 thanks Debra Herndon
