Honestly it doesn't really sound too terrible a weight for the size. Just remember a huge Hoggie might be 300+ grams. They are not like BP's.
Have you tried thawing the mouse pinks with another prey item that has fur? We had the same issue with a hoggie and when we started thawing the mouse pinks together with the rats for our other ball pythons, she slammed them. Now she is taking two pinks in a feeding without any fuss. I just lay them next to her and she eats them both. Can't guarantee it will work for you, but it's worth a try. Good luck
