although i don't have the dual fuel, i can speak to the burners and customer service. i doubt it matters i have the pro grand, but features seem the same if memory serves...
i'm guessing you have read about "incessant clicking" on the burners..this issue has been dealt with and even at the lowest setting, when it cycles on and off, the ignition is fast and efficient.
i had to contact customer service on three occasions and found them helpful and courteous.
my $.02, adjusted for inflation

That is helpful, thank you. You haven't had any problems w/ the 'star' burners emitting too large of a flame for smaller pots and pans, have you? This was another complaint I've read about, however, I find it hard to believe the flame could not be adjusted??

never an issue, and it simmers well...adjusts as needed for the task

Good to hear, thank you!
