I got mine drilled pretty similar to the way you described. I used it in a travel league at a house I never bowled at before, reacted alright, little over/under for my liking. Used it last night and took a 2000 pad to it and it was good for 1 game, then as the carry down started happening, my over.under reaction started to happen again. I'm going to take a light 1000 pad to it tonight before league and see how it reacts. Might end up doing 1000/polish or something similar in the future
