My friends got an XXIX and it hits pretty hard and has a nice switch BUT because it's a hybrid expect juice in your tube when using an atty that likes to leak past the o-ring. One of his VTC4s has a good deal of juice under the wrapper.
I have a Stingray black copper which has two sections but the thing hits like a tank, switch is pretty clicky though so not my favorite. I just ordered a Munstro clone simply because it looks good in person and comes with two 18650 tubes, one copper and one brass, and an 18500 stainless tube. Pretty good deal for $40, as long as it works well.
