I just got my SPS 62 last week and I love it! It spools as fast as stock even with an Auto and 35" tires and is great to tow with. I run the SMARTY on sw3 when I tow and It has been great. Egt's are down also when towing.

 

That sounds good Big Horn, I think you just made up my mind for me. hahaha

 

That's not really possible, the increased inertia from the heavier turbine wheels will make it slower than factory in any case from idle to spoolup, but i understand the concept you're trying to express, it will light quick enough to please!
