Digital BW, The Print

For eons I've used Tri-x (the 400 not the 320 pro) and HC110 dil B 
for 4.5 min in distilled water. Keeping the dev time low to prevent 
highlights blocking and making sure to give enough exposure in the 
shadows.I took up this 'formula' from Adams' The negative and 
Picker's book & newsletters. 
This has worked well for my silver prints.
I've packed up my darkroom and now that I'm scanning my negs (for 
1160 quadtone printing/MIS) I find the grain objectionable - it's not 
crisp and it's big.
Any advice on adjusting my 'formula' or....a change ? I'm not too 
sure about changing to a chromogenic film as on occasion I may still 
want to have a silver print made.
thanks
Frank
