Looking at grinding my own ground glass for a recently acquired 8x20. No sense starting too small...

The existing ground glass is quite dark, and so looking to do something brighter.

Given the effort involved, is it worth the additional cost of using borosilicate glass rather than soda lime glass?

I have read the various articles include Ian's on this site and the instructions on the Hopf web site. Any other insights or cautions?

I did pose this question on another site that focuses upon LF photography, as well.
