Which one first?

Just because I cannot leave it alone, am going to update the suspension on my Norge.  Won't get away with convincing the wife to let me do the front and rear at once  so one then the other.  Which one is more bang for the buck?

Looking at the Matris F15 fork cartridge kit  and the Matris MM107.1KDIS for the rear shock.

If you ride 2 up, get the shock first.
If the back seat driver can feel the difference, tell her your neck and shoulders are copping a flogging.

Sounds good, payday tomorrow
