Digital BW, The Print

I mistakingly posted this question on the inkoptions list, it was meant for 
this list.
I am about to mat a group of inkjet prints.  What I have been hearing is that 
I should use nonbuffered rag board because I am using dye inks.  I was 
planning on leaveing a 1/4 inch border around the image, so that the board 
would not touch the ink.  I can't see how this would cause a problem, or 
would the entire printed sheet,LPM, be at risk on a buffered matboard.
In the past I've used Light Impressions Westminster rag board, usually the 
buffered variety, or teir Exeter brand which is buffered but not 100% cotton 
rag.
They offer the buffered varieties in an 8 ply depth which I find appealing.  
The non buffered only comes in 4 ply.
Any thoughts?
