Digital BW, The Print

Does anyone in this group have any experience using PremierArt Luster  
Rag Smooth?  I inquired about a rag based luster paper at my local  
supplier (West Photo), and they recommended this product - they said  
it is relatively new.  So far, I have been happy with the results,  
but due to my inexperience relative to the members of this forum, I  
am wondering if there are any thoughts why this paper might not pass  
muster.

The following is a link to the spec sheet on the PremierArt website.

Quick specs:

weight - 325gm2
thickness - 23mil
Texture - hot press
Surface - luster smooth
Paper type - 100% rag
coating - single side

Additionally, could someone explain to me the difference between cold  
press vs. hot press, besides the obvious temperature difference?   
Thanks.

Best regards,

Josh
