You want me to repeat Bob Maxey's "famous last words"?  

BS!   :-)

It's your show and you bring what you like:  Cardboard mounts and film
that does not depolarize light.  If you insist in using film that
depolarizes the light, then grab the polarizing filters and stick
them in front the lenses.

The 716 does, the 116 does not.  The 716 uses 750W bulbs, the 116
uses 500W bulbs (like the Triad).

>Yes, the Triad does.

In the TDC 116 with 500 W bulbs such cooling is not needed.

These projectors have heat-absorbing glasses too.  I think Greg W.
said it best.  My own words:  If you are going to lose the
light anyways, why not do it before the slide so you can get the
extra benefit of reduced damage to the slide?  (Assuming of course
that your slide does not depolarize the light - if it does, you
have no choice)
