Haven't got a LT, but have an EVO and Provari.
Have the original EVO, never had any issues with it since day one, and outside of the reviewers, I have one of the first available here in Canada. Rock solid, and love the DCT's on it. Higher ohm singles and atty's work very well as well. Not part of the original post/question, but the Provari obviously handles everything exceptionally well.
If you go with a LT, make sure you get the adapters so you can use everything on it. (510-ego, 510-510 sealed and unsealed, etc...)
