Sound Deadener and 6x8 to 6.5 adapters

After 10 + years of use of B-Quiet (or the previous Brown Bread), it is easy for me as a dealer to make my choice.

Ok now Im down to damplifier or damplifier lite.

I was planning on spending max 150.

For 120 i get 60sqft of the light

and for 155ish i get 60 of the regular.

Im not sure whether I should sacrifice the 1mm and for 35$

How much of a difference would I notice even?
