Ill go with the 60w version for sure. I have a Dna200, Dna133 and 5 Dna40's, one getting the Dna60 board as we speak. I have no interest in the Dna250 and the Dna75 is limited in the power delivery department and is best run around .50 and under. The 60 gives you all of the perks a Dna200 has and can run up to 9 volts on one 18650 which works best for me.I want an Evolv Custom mod bad but dont have the money anymore these days!! If anything, I would only be able to get one.. Would be hard to decide on which lol
