Emir, I noticed in your posting that you're not using any benzo, any particular reason? Also, if you can find some HC110R (replenisher) you may find it works better when you need a "hotter" developer.
-- (IMHO) benzotriazole is lovering fog but it is also eating the actual image. Plus, HC-110 is low fog developer. Plus, at the low temperature I use the fog is lower. Plus, you never know if the fog is actually a problem. Some of the rolls have no fog at all. All in all, it is better to find the development compromise where fog is still manageable.
-- I have seen the replenisher online. Have you used it as a developer? What are the dilutions?
