I've not used the Kahtoola KTS myself, but friends have, and its performance is similar to the Hillsound Trail Pro Crampon but at twice the price. If for whatever reason(s) you want to go with the Kahtoola's, make sure you select their steel version. The aluminum version will dull rapidly in mixed alpine environments. Is either one suitable for the Baldy Bowl? Well, I can't speak for others, but I would use either of them for myself.
In another post there were comments re: using gaiters to hold microspikes on. I suppose that would work in a pinch (better to use a piece of paracord or shoelace over the instep) but at the risk of stating the obvious - it defeats a purpose of gaiters. A properly attached gaiter helps prevent snow from being forced up between the boot and the lower leg. It also helps keep out water if you punch thru a snow/ice-covered brook/river - not for too long, but a few seconds is often all you need. Putting them over the crampons/microspikes will also create a slippery surface, possibly cause snow/ice to accumulate around the strap, and will accelerate wear on the strap. Personally I won't do it, but hey - some people wear their underwear on the outside and make tons of money doing it, so who am I to say?!
