I've stuck with the YA packs since the first time I tried them. I've been gigging with the KW since its release. I've tweaked my setup steadily, but always quickly come back to something from the KW pack. I basically tweak elsewhere now, and leave my cab settings alone. I run stereo, two Cele F12 DIY cabs on stage for myself, direct to FOH, and monitor with IEMs about half the time. I love the sound, feel, and gigging experience with this setup, it's inspiring to play, easier to fit into a large band mix, and I always get compliments on the my sound.
