Broke down today and bought a pro tank 2 to see what the fuss was about. Filled it with some black licorice juice ( both from local B&M) and WOW! Got an evod tank too and dig both on the MVP. My iClear 30 and ARO are now nice back ups! Also got some great tips from the swell guy at the shop. Unfortunately, he let me try out his personal mech mod with drip tank, and well, I love my MVP, but still want more toys!
