After having worn my Pitons regularly for a couple months now, I will have to say I am very happy with them! They smear as well as any other shoe I have ever owned (I have only ever owned 5.10s, but numerous different models over the years), are surprisingly good at edging (even though I bought them large), and as hoped, great at cracks (to a point that I have had trouble removing my feet from jams in rough sandstone!).
The sizing is true, at least relative to the last that was used for the Huecos. I bought the Pitons a bit larger than my other 5.10s (I wear a 9US street shoe, and bought size 7.5US/40EU Pitons) and they fit really confortably with a pair of socks (no extra space in the toes, except next to the big to, but I tend to have a symetrical-shoe-shaped-foot).
The only two things that could have been better for me personally:
1) They are a bit wide for me (without socks, I would have to lace them as tight as they go, and then some...), even though I don't have a particularly narrow foot.
2) Lining! I absolutely love the lining in my Huecos, and would definitely miss it in the Pitons if I had bought them a bit smaller and didn't need the socks.
Otherwise, great shoe 5.10!

I have 1 pair of the original models (maroon) and 3 pairs of the 2nd version (EVA heel). They all fit like a glove, and I have had little problem with smell (all climbing shoes smell after awhile...) I am a bit dissapointed to see that they have abandoned the EVA heel after such a short run though. I thought it was an awesome idea, and it is so much more comfortable to land on when bouldering.

I am now on my second of these ropes, and am so greatful for how light they are. My 1st was a 'classic', which I found a bit sticky feeling and stiff when new. My 2nd is a super-dry trio-safe, and is an absolute handling dream!

A very good carabiner, with an excellent size to weight ratio. Definitely large enough for just about anything you could possibly want to put into it. The locking action is also very smooth and responsive. Only 2 drawbacks (one being quite significant). 1) the price, although average for a large locking biner, is somewhat steep compared to the Screwlock. 2) there is no way to "lock" the sleave to prevent accidental twisting (some others have extra notches or little balls). I see this as being a reason to maybe not use this carabiner with a Munter hitch.
