I'm considering buying the KitchenAid 7 qt KSM799WH Commercial Mixer but find very few reviews and a lot of comments confusing the mixer with another KA 7 qt.  This 7 qt commercial mixer is the only KA currently being built with a metel casing protecting the gears.  I've been using the Pro HD model and since I've been making bread and pizza dough have stripped the gears several times after cracking the plastic casing a year ago.  We're currently waiting for a new plastic casing to repair the Pro HD.   

Although I'm a novice, I weekly make fresh pizza dough for our family.  Lately, I've mixed from 1-5 batches of  an authentic Vera Pizza Napoletana Dough recipe.   I understand that is a low kneading type dough?  Each batch weighs only 1 pound.  Typically, I'm making only 2 pounds of dough every 2 weeks.   My current KA Pro HD cannot handle the pizza dough w/out stripping the gears after a month or two of use so I'm ready to move on.  I'd considered a Hobart N50, but one very good youtube review said that if I was going to be making even 2 small batches of pizza dough a week, I'd burn up the motor.  If pizza dough will burn up a Hobart N50, which will fit my KA attachments, then that is probably not a good investment for me.   Not sure where I'd read that someone was mixing several pounds of pizza dough with the new KA 7 qt Commercial KSM799WH Stand Mixer but it gave me hope of going with that model again.    

I understand that Avancini brand spiral mixer is the only Italian made mixer available in Canada or SF, CA but also read that it needs a minimum of 3-6 pounds of pizza dough to run properly.  That's not a good investment for me if often I'm only making 1-2 pounds.  One Avancini user said he uses his KA for the smaller batches, which sends me back to considering the KA. 

I have a KA Pro HD and know that all of the KA's more recently made are built with that plastic casing, except for this newer model KA 7 qt Commercial model KSM799WH with the orange cord that only comes in white.  This is what I'm hoping that I'll hear from, owners of the KSM799WH model and how it will handle pizza dough.  How many pounds of dough can it take?

I also enjoy making pasta, sour dough, foccacia, French bread, and crossoints and want to know if this KSM799WH model will handle that type of bread making? 

Any videos of this machine in action, aside from the KA demo?
