Just got my new stock and was wandering what rear rest would give me the best fit? Rabbit eat/bunny ear/mid ear/etc... My home made bags are not right and they slide and move on me so have to re-adjust every other shot

I have never had a real rest and no local places here carry any so need some help. Read the manufacturers' help and they said to make sure it's a good fit to be very stable for the rifle

I appreciate the help/input
