I have a Convict 650S in green, running Stainless Steel braided cable to ekowool build using dual coils. I love it. Currently running VTC5 2600mAh, HE2 35A 2500mAh and just picked up an MXJO 2500mAh 35A. I've got a copper Tugboat tip on it (insulated so it doesn't heat up unless I'm really cloud chasing. They're worth it for the money and look really amazing with the SS Braided wicks. All copper contacts and made from solid bar so there are no seams or welds to crack, the hybrid drip models have pyrex tanks (thank God, I know I've dropped mine a few times and no cracks yet). The only step up IMO from this for cloud chasing would be the Warden (unreleased triple coil 26650 model due out soon from Convict Vapors), the SHU from them that is drip only or getting into box mods, love the hybrid drip though (Genni style) and am at a quandry myself since I love my 650S.
