This club is so good that I now only carry a "sunday bag, the Q takes the place of all the irons I would normally carry from sand wedge to 6 iron. I supplement it with a putter, chipper, and 3 longer clubs (ie 3 & 5 hybrids and 3 wood). The more I use it the more I can accurately control distance and there are times when I just grab the Q and use it for all shots including putting.
While it is not (yet) regulation, for casual golfing it is freeing to not have a larger bag of club to deal with, light and agile, simple and easy.
