Welcome to the group!
A lot of folks scroll right past new member posts so your questions may not reach the right experts. Suggest you restate your questions under one of the more specific forum pages.
To make it easier for folks to relate to your situations, consider adding a signature line similar to the one below so your rig and hardware can be clearly understood.
Sorry, my rig is different and I can't address your specific questions. Good luck and, again, Welcome!
