As with all gear, the choices are dizzying. I have a cheap pair of Mountain Smiths that I have use for years. Made of aluminum, twist lock, shock absorbing and weigh 20 ounces or so for the pair. I would like to get a new pair of sticks for both me and my wife. I prefer the cam lock over the twist, not sure I need shock absorbing and conflicted regarding aluminum or carbon. Probably the main reason I am even considering carbon is that maybe, just maybe, they are a bit quieter than the aluminum ones (when I inadvertently hit them together). Appreciate any and all helpful advice on type, brand and model. Thx Pete
