Pros: Light, adjustable, safety release, changeable baskets
Cons: Trigger S Strap is easy to lose and expensive
I was lured to these poles by the twin siren-songs of adjustability and carbon fiber. I've always been unsure of how long my poles should be, especially for different situations. I just couldn't bring myself to buy nice carbon fiber poles (for the low swing weight) and then butcher them down to a single permanent size.
In use, these poles are really nice. The SpeedLock adjustment is quick and easy. The lower shaft has centimeter markings. The SpeedLock levers have a nut that must be adjusted finger-tight in order to prevent "creep" in the pole length. So far, the locks haven't gotten in the way. The Trigger S strap system holds the pole really positively. I'm starting to like that a lot. I haven't tested the safety aspect, but it sounds good. Changing baskets isn't too bad once you realize how they're threaded.
All in all, I can't imagine needing or wanting a nicer pole for resort use. If you've got the money...
