what's wrong with plastic? that's what I want to know
Seriously though...that's pretty minimal. It looks like you probably do a lot of driving with the putters.
For my use, the predator has a hard fade at the end - vs a longer fade for the teebird. If you can throw the teebird in that slot, it might prove more useful being able to throw a long fade/hyzer. I believe the champ is more overstable than the dx versions. As for the Rocs, if you like 'em, no reason to not throw it if it works. Does the KC do a great anhyzer/turnover? If not, then the comet might be a better companion since I know it will.
I admire the simplicity of the bag. Couldn't do it myself.
