Tuttle?...you're going GoFoil?...YEAH!...go GoFoil!....
the aluminum plate is a bit heavier than the carbon one that GoFoil sells BUT you dont have to use washers under the bolt heads because the aluminum plate has counter sunk holes for the bolts...if you get the carbon plate fron GoFoil you MUST use the supplied washers and little longer bolts or youll crack the plate...not a problem...unless you accidentally drop a washer and it bounces across the sidewalk and into the bushes at Malibu and...aaaaaaaah CRAP...now you gotta go Homedepot and hunt down stainless washers with the correct size hole...hassle...
you never notice the weight difference until you have to go back to the aluminum plate and..."why the hell is this thing not pumping back out like it usually does???...and MAN it feels heavy today"
