I just bought a s211. Had it out for 5 days and love it. It doesn't have quick surf but the dealer said it was a waste. Filled both quick fill ballasts and surf side bag 100%. 10.4-10.8 mph depending on how many people in the boat. Threw a killer wave with just me surfing and my wife driving. I was able to go ropeless forma short time but am blaming my size and board choice as other riders were able to surf rootless for along time. Surfing a ronix mellow and weigh 260lbs
