I'm adding a few sections of fin tube to a new addition. Is it better
to hang pipe (j hooks/straps) under perpendicular beams/joists or go
through? My concern is both adequately supporting the pipes, and any
potential difference in insulation (as this is a post and beam
construction and fairly close (2') off the ground.) Thanks.

I would hang the pipe under the joist. Trying to drill a straight line of
holes will not be easy. Trying to feed the pipe threw the wholes will even
be harder. I guess it would weaken the joist. Most the time the pipe is hung
under the joist. They make a plastic pipe hanger just for that purpose (Most
people call them flying ass wholes) I would put about every 4th joist for
3/4 copper
