mikenehrkorn, thanks for the response.

Do you have the 750 lb (20"x20"x50") bags? If so, what kind of fill times are you seeing? I can deal with 10-12 minutes, but anything over 15 minutes when you're ready to hop into the water makes me cringe a bit. I am sitting at about 6-7 minutes to fill the 400 lb bags I have now, and the 750s being ~2X as large I'm guessing they should be somewhere in the ballpark of 11-11.5 minutes to fill?

Thanks again for the information
