I do not think there are too many of us Manticore owners on here. For me I keep it simple... I start with a ground balance. I have the TID screen wide open. My recovery speed I keep around 3. If I am over a lot of iron I will bump that up and slow my swing speed down. My sensitivity I keep around 19-20...just depends on the chatter I get.
I also will swap out the stock coil for the M8 coil in areas of high iron.
