Just been looking at the guide, and for the most part good stuff but...
Removable, ski-type baskets tend to fall off and get lost
...is news to me. I've only ever used my actual ski touring poles and so I've always used ski-type baskets, and have been using them for about a dozen plus years for walking, and in all that time have never lost a basket. In fact, taking them off for whatever reason has always proven a bit of a beast! (with both Leki and BDs).
I prefer (non-powder) baskets to cones, I don't find they get in the way and they give one helluva lot more support when using poles to vault bogs, or on snow.
The one vs. two thing... well, two work better for keeping weight off your joints, but if you've only one leg that needs special looking after one is enough (use it on the opposite side to the weak leg) and that leaves you a hand free for something else. Like a map, camera, GPS. For me the real downside of poles is having my hands full, so even though two are often more effective for keeping off the weight I sometimes find one preferable in practice.
My favoured ones are ski touring poles (a bit stronger and not covered in (IMHO) mis-features), and for me I can use them skiing too) which come in pairs anyway...
