Tim,
If your reply was to SteveL then I think you might have misread him. He's an oldschool racer, In fact he owned his own RC Business a few years ago. I think he is just curious about the two types of packs and how they compare. I know a few tbar guys in my club that converted over to the "brick" style have made similar comments about the Speedzone pack.
Gavin did good and we will remember he did it first.
Steve
