Just got my LT 4s today... as much as I knew about them going into it, knowing their weight, knowing what people said about them... none of it really prepared me for actually holding one and feeling how insanely light they are. Amazing! And I am impressed with the locking mechanism thus far (in-house testing only), and am pretty sure that being able to use a small keeper cord will be more than I'll need for these. Although I've always used poles with straps, I actually prefer the feel of not having them here. Cleaner, less bulk, less in the way. Great product! (And nice that they do make them w/straps for those who prefer them.)
Oh. And with a nod toward the "Lightrek transportation" thread... I got the shorts, and they fit diagonally into an Exos 58. They do fit, though just barely and with a little finagling, into an Exos 46. Incidentally, the poles fit easily into a Jam. My plan is to just put them in the pack, then pack my stuff around them for transportation.
