I have a number of Pyramid balls and some are drilled strong I have both pin up and pin down and all work well . I have found that changing the cover surface to match your game to the lane conditions is very easy. So I think you will be very happy  with your new ball.

I've watched guys come in and shoot decent sets with their stuff. One guy even shot 880 (I believe) with the Blueprint Pearl. I, personally, haven't been too impressed but that's just me. They seem to handle the fresh pattern really well but tend to struggle in the transition and chase in periods. A gentleman I drilled for had a Blueprint Solid and he just couldn't get it to roll through the pins well; multiple surface changes, weight hole, put him under oil, put him on burn, just didn't match up.

One aspect is they seem to have that Old School early and rolly motion where if not properly adjusted can lead to rolling out too early and deflection. That's just my .03 cents.
