What Tom said
Assuming the nut slots are cut properly and the frets are leveled (which should be the case with an Emerald), a basic setup relief adjustment/saddle height takes very little time and skills. Check videos on the net.
I would bet that you won’t have to change anything going from X-Light to Light with a carbon guitar.
If I remember correctly if you want to buy a second saddle you need a GraphTech Black Tusq XL PS-9280-C0 Acoustic saddle compensated 1/8"
