Scanning 11x14....Epson XL10000 the way to go?

I suppose even if you had a 300 Apo-W there would be no point to scanning at more then about 3,500 PPI.

What is the maximum resolution with the large drum on the 7500?

I think you are about spot on. No way in the world for one to get more than 60 lppm (3000 spi) on a piece of ULF film in real life photography. In fact, it is virtually impossible to get 40 lppm (2000 spi), even with the best lenses you can find. For that reason I think it is a total waste of time to scan a piece of ULF B&W film at more than 2400 spi.

Could be wrong, but I believe the maximum resolution of the Howtek 7500 is 5000 spi, or same as the 6500.

I thought the resolution was lower when using the large drum.

It is, it is 2500, I believe, maybe someone who has one of these could confirm. However, 14 inches times 2500 = 35000 pixels, or in round numbers, a 100 inch print at 350 dpi.

Did you want to make something larger?

The 7500 has a couple of advantages - the drum makes for very sharp scans as the focus is static (on the drum surface), the liquid mounting helps with scratches and dust, it has aperture-grain matching and the PMT sensors are fantastic. All you need is an experienced operator or some of your own testing and you're good to go...
