Hi, I love my first serious light purchase of an eagletac d25lc2 clicky that I use as an EDC. After looking at several other single 18650 options for my next light I could not find one that is significantly better for a decent price. So now I am looking at the new version of the TK35. Sounds like a lot of you own or have used one and I am wondering about the form factor. How is it to hold? Does it require a holster or would it be possible to carry in a pocket? Are there other side by side options to consider?
