I have had both balls for about a year and a half now. I have both drilled the same with a 5x5 drill and the mass bias in the strong position. I have both polished with black magic polish in the black bottle. I find the erase-it will pick up when the lanes get too dry for the ER.  They mirror each other in movement. I can move back to where I started the night and throw the erase-it and get the same reaction I had in the first game with the ER.

The ER reads the mids a better than the erase-it, both are fine balls that will cover a lot of boards.

To my eye I have always thought they were nearly the same in the amount of oil they could handle but that the ER had a more angular backend while the Erase-it was more even.

Erase it = Strong medium heavy ball, Trauma ER = stronger medium heavy.

PS note ER is a mass bias ball Erase it = symmetrical.
