My white & black ZA11 was flawless.
Actually i guess you should consider Rival 300 and G402, as these are among the biggest mouse for palm grip.
The G502 had an annoying button where my thumb rested. I couldn't really work around it.
It's something I would have to adjust to, from palm grip. I tend to do a hybrid grip on my DA 2013 since it's not long enough.
