Ok, churchy - agree that beto lovely b/a to work with - blue grit kill suction more than beto ?
Micro is nice stuff. Id say wba is probably slightly better since they changed the micro. but micro is more cost effective imo and in most cases can be skimmed an hour later.
Blue grit is just porridge
Only ever skimmed over blue grit once as the customer used it as he wanted a good job. He didn't stir it and the grit was all clumped together. Swallowed skimming to cover it.
