Manual valve body benefits?

I honestly went with the full manual valve body to avoid having to screw around with kickdown linkage. I did it basically for that reason alone. I am very happy with my valve body. they are right though about it shifting smoother under load. if your coming to a stop and down shift off the gas it will slam pretty hard. ive had it knock my sun glasses off. but when you nail it and shift its right frickin there.
