Fiddleback on the inside or out?

I picked up some nice crutch pieces recently and have started to process them for turning. Red and grey iron bark and some pink bloodwood. Most have fiddleback that's why I grabbed them. Where do you guys put it? Inside or outside of the bowls? They were not huge rounds so should turn 300x 1500 max out of them with a section of good fiddle. I 1/4 sawed some to try and keep more but the loggers cut where they cut and many I didn't have a choice where to rip.
Cheers
