I have the Ti, since I too like scissors, and have little need for a gut-hook. Also, i bought the extra bit kit, so I can carry a dozen bits around, making the second bitholder of the XTi superfluous.
As for the sturdiness of the bits and holder, I've used mine pretty hard, to the point of stripping a coupla screws by accident; the bits and holder survived unscathed. Don't think ya need to baby 'em!
I carried an original Wave for ages, but the Charge Ti is now my EDC about 90% of the time. Yeah, it's that good.
