"Are you talking about the carbon fiber version? I have the aluminum version and find them more than adequately strong. I'm about 205lb and use them very aggressively. (Mind you, I have other issues with them, but not that.) So if someone knows a way to change the unchangeable tips (maybe so, see above), I wouldn't hesitate to give it a try, at least on the Al version."
Todd, I did not realize there was an Al version, if that's what Martin is referring to then I agree with you completely!
Dale, the snow baskets indeed add more stress to poles but maybe I should clarify that it's not "more" in the sense you are summing up all the forces. I am referring to the vector loading that snow baskets can potentially add that the pole was not designed for. If Martin is referring to the Al version then I'd imagine that would not affect much, if it was the carbon version I would not suggest it.
