Digital BW, The Print

I'm a recent convert to QTR (and love it so far).  I use a 2200 (with 
mk inkset) on a WinXP platform.  There are limited tone curves 
available and it seems many papers are not yet supported.  

I have printed a fair amount on EpEnhMatte, but would like to use 
other matte papers for which no tone curve exists (at least in the 
v2.1b download from Roy's site).  I was wondering what the results 
would be like if you printed on another matte paper, such as Moab 
Entrada Bright White or Somerset Photo Enhanced Radiant White, using 
the EpEnhMatte profiles?

I am assuming there will be differences in both tonal response, Dmax, 
and color when changing from one paper to another.  

When printing color images, I know there can be significant 
differences between papers, but I thought perhaps these differences 
might be more subdued with B&W or toned B&W.

Any suggestions on how I can get good results without custom tone 
curves for these papers?  

Or how I can create my own tone curves?  (I have a spectro and PM5).  

Or, is there a repository of tone curves available somewhere?

Thanks.....and Merry Christmas!
