Everyone has their atty preferences. I've only used 510s and 901s. I like them both, but I do notice a bit more vapor production with the 901s, but they are quick to leak. No matter what atty you end up using, you should look into a drip shield. I don't know if the LT has a
juice catch, so a shield would be just the thing to keep your LT safe and clean.
Price wise, I don't think there is a big difference, if any. Go to your main vendor's website and compare prices between the ones you want to
buy. Don't forget to get a drip tip.
