Okay so I got over that fear of 500 degrees on the pipe. I've learned alot here over the last month about the proper ways to keep and maintain a smokeless fire even in a 30+ year old stove. I guess it makes sense that a hotter firebox would be easier to control but I guess there is a science to it. I'm guessing the splits must reach a certain point in their mass whereas the slightest air adjustment can control the burn? Tonight I was able to dial in any temp from 450 upwards of 750 and the stove pipe would react and settle within 5 minutes. 750 degrees was rather impressive...talk about radiating some heat! I think bricks in the hearth thought they were being cured again. 
Thanks for all the good reads and someday I hope to get one of those newer designs for my second hearth that currently sits empty.
