I try to leave at least 1/4" of thickness behind the rod.
That's why I use shallower rods, such as LMI and Grizzly. The hot-rods are nice, but their depth requires a thicker neck. With an LMI or Grizzly/BBG/Allied rod, I can make the neck stock (not fingerboard) 5/8" thick, while with a Stewmac rod it needs to be 3/4" thick. It's only 1/8 of an inch (~3mm), but it's enough for me to notice anyway.
