The tubes are 304 stainless of .049 wall thickness and no need for inconel
for them.  But, they hang off of 18" of header pipe so the temps are fairly
cool by the time they get there.  I also have on the ends some 0.064
stainless that I squished down the ends to make a fish tail.  While its not
as quite as the spintech, its lighter and much cheaper.  My holes were 3/16
which is probably a bit on the large size I think I would go with 1/8 next
time.

No signs of deteriation after 120 hours.
