I have never seen a bulk roll of it or tried to order it this way,
but I guess it is available somewhere like this.  Call Konica?

I never use HC-110 for anything, so I can't recommend any times.
I have used only Ilfosol-S and Microphen, extrapolating times based
on Konica's developing times in Konicadol in the data sheet.

Tech Pan goes to maybe 660 nm.  It is decide NOT an infrared film,
as its sensitivity is nil at 700 nm, the border of the near IR.
What is interesting is that Tech Pan does indeed lighten foliage
a bit.  It does nto turn it glaring white; the effect is more like shooting
with a light green filter.  At the same time, deep reds and woodgrains
tend to show up more like one was shooting through an orange filter,
because they are lighter and with bolder detail.  The odd result of this
increased exposure in the lgreen leaves and in the reds is that one
tends to print a bit deeper, resulting in slightly darker skies, almost
as if one had used a UV or pale yellow filter!  All of these effects
are subtle, but they are there.  The only no-no with TP is portraiture,
as the combination of ultrahigh resolution and extended red sensitivity
is pasty complection showing every skin fault and pore!  How to make
your girl friend livid in one easy lesson!

A very good film, it is best if you use it for everything for a short 
while to learn all its foibles.  I love the stuff, and will be using more 
of it since I seem to be doing 35mm more, lately.

Hope this helps a little,
