Pros and Cons of Toytec ULK

I have now fully decided that I will spend my money on the ultimate lift kit. My sound system will wait because I listen to mostly rock and little rap. so that aside, to those who have the Ultimate lift kit, what are the pros and cons?

Vibrations?
Allignment?

Im getting the TC UCA's so allignment isnt that much of a big factor.
and to the guys who are saying, this kid is spoiled for having his parents pay for his mods.
My parents are not paying anything. they asked me if I wanted them too, but I told em that I wanna buy my own things for my own truck.
My christmas wishlist has only 2 things on it. 3 4" PIAA 510 lights and the prerunner bar. Everything else, Im gettin by myself. so please dont call me a spoiled brat.

but back on topic, pros and cons of the ULK please.
