Affirmative. I use a #20 drill (.161"). There are lots of .156" spraybars made, but very few .135". More options when you break one, maybe will keep you flying instead of waiting. When the OS NV assembly gets crashed, it can start working funky, not following the tweeks, changing in the air, etc. The ST types either work or are broken, nothing in between. That's good, IMO.
