hi meeems,
re: the LT : for the last 6 mos I been using ce2 type clearos, small 2.5 visions, large tank-like visions, the e-turbo, e-go, vision stardust, they are all pretty much the same, no matter what name, between 2.5 to (supposedly) 3 ohm ... recently I went back to the old standard 3 ohm boge, and I forgot how good they were ... I'm getting better flavor, th and vapor with the good ole boge
and I can push it to 6v with the LT and the IPro ... tbh, I've never used anything that restricted me from getting to 6v
the IPro does NOT restrict or reset the voltage, so you can blow up a lr cart at will
I never saw the need to use lr with vv, altho I did use a lr atty with my ego mega setup
the IPro is a bargain for the price, none better vv afaik ... even better things coming this year
I see you frequent DV ... I have an xl3 with an updated top off a mini which gives me 4 ranges, up to 4.2v iirc ... not bad for under $30
best luck
