John, your comments are valid, but not much of a concern. The ridge pole is a piece of lightweight hi-grade PVC pipe, crimped on each end at a precise angle to form the top and side angles for the entire structure. The pole tips fit in the ends of the PVC pipe. Any brand pole tip should fit in, particularly since the tip and housing tend to taper, so they will fit into the PVC up to the size that wedges squarely in the PVC hole.
The issue is if your poles are fixed or adjustable. The shelter is most taut, and strongest, when the poles are 130-135. If you have adjustable poles then no worries. But if you have fixed-length poles then there is some sort of adapter. I haven't seen it but I imagine it is some sort of extension pole for each side so that the shelter still is taut. If you change brand of trekking pole and need the adapters you could get them.
I set up my shelter leaving the mud baskets on. Haven't tried the snow baskets, I share your concern and probably would want to remove those before setting up the shelter.
Also, I've found flip-locks much easier than twist-locks for setting up the LH. You have to pull up hard on a pole section and then tighten it to get the walls really taut, that's a PITA with a twist-lock.
