I have 6 LT's with my favs being the SS versions. They hit harder than the original LT's that I have. I know my LT's came from different batches (some have an apollo logo, some do not and 1 came from TW) and there are minor vaiances in most of them. The logo apollo ones are midline, the black mini with no logo from apollo is at the bottom and my full black from TW is almost as good as my SS versions, though they beat it in loaded voltage by ~.2v
I just ordered a crapload of batteries, so I will not be the first with a version 3, but I am sure I will have one before too long, likely a chrome version.
