Hey for $35 + $50 + $(s+h)=A pretty great deal since you already have the edge!
$35= upgrade price including the black gryphon case.
$50= one custom file 87 oct perf(what most get)
Not to mention great mints when you get the box back.
Also great customer service.
Just trying to help.
X2 what Jack said and adding in that if you make changes do them in little increments it's easier this way.
Use a note pad to remember what you thought was best.
