Response to Xtol update... dreaded Xtol failures

I would play it safe and not use XTOL if I owned a lab. Most commercial customers would not see the difference in D-76 and XTOL negs. A serious shooter will. There are many variables and the scope of the problem is unclear. No doubt, some people experienced legitimate failures. Failures are mentioned more frequently with newer tab films than traditional films such as Tri-X, FP-4, Verichrome, Plus-X. I believe APX may also require XTOL to be fully active. It's been mentioned that the activity of XTOL can fall rapidly and is affected by PH. The package problem is well know and should be solved.
