Edge vs. Quad shifting in similar power levels?

[sbrew]

I've had the Edge with attitude for a couple months now. I have been driving in level 4 smoke 5 for a couple thousand miles. The shifting has improved, but I think this improvement fooled me into thinking it was shifting correctly. I recently switched to level 3 and the shifts are sooooo much smoother, so I'm leaving it there. But I sure much the extra power of levels 4 and 5. This brings me to my question. I've heard that the quad 125 shifts real well. Has anyone compared juice level 4 or 5 to the quad on 125. I saw that quad doesn't do anything to the tranny, so I'm wondering how it could shift any better. Quad, if your out there, I'd appreciate your input. Also, if you talk me into it, is there any guarantee if I don't like the shifting. I have been reading all the threads on the comparisons, but have not seen these two comparisons specifically.
Thanks,
Shawn

My 160 box shifts great if I leave it on high, or if I do toggle between modes I work my way up to WOT through a little driving. You have to remember 160+ at the wheel is a lot of power and a lot to ask of the tranny.

Buy a 125 Quad box and try it for 30 days. What do you have to lose?
