QTR-Quadtone RIP

i have two questions for everyone. i hope you can help. 

i've been test profiling 3 papers with QTR for a couple of weeks using the 2880 instead of the 
1440 resolution setting:

1- is there any real-world difference between these resolutions, or have i been using lots 
of ink for a trivial difference between them?

2- would you recommend that i continue profiling using 2880 or switch to the 1440 
resolution setting? (i think the answer to this question would depend on the first one.)

thanks in advance for your help.

I guess that depends on printer and ink. For my epson 2100 with UT3D 
I'm in the process of switching over to 2880 since I get better Dmax 
and smoother prints. Not that the 1440 prints are bad, but the 2880 
prints are just that bit better...

I don't think that 2880 dpi means more ink. One has to reduce the ink 
limit substantially in order not to lay too much ink down. The main 
setback is that printing is slower.
