I posted this in another section, but, since it is about a Hammer ball, here you go!  I am just looking for all the help and advice I can get!  Sorry about the double post!  
OK...so this is all new to me. Back when I bowled seriously (10-15 years ago), I don't remember sanding my balls. We would just stick it in the Luster King (ROCK ON!) and start bowling. I have just gotten back into bowling and purchased my first ball in 20 years (16 Lb. Hammer Black Widow Bite that I think was sanded using a 4000 grid pad). After about 10 games getting used to the ball, I am now consistently throwing around 190 (with a high game of 234 with the new ball). I am a pretty old-school bowler (righty who stands between the center dot and the dot just left of center, throws straight up between the 1st and 2nd arrow on the right side and lets the ball arc into the pocket; however, I would like a little more of a snap reaction as opposed to the arc). I am having issues with leaving A LOT of 7 pins and 10 pins despite hitting the pocket pretty flush on most shots. In fact, my past 6 games were between 175-235. I went thru and figured my scores if all of those 7's and 10's would have fallen and I would have been between 220-270. So, here are my questions (FINALLY!). 1.)Would adjusting the surface of my Bite help with the reaction thru the pins? 2.)Would adjusting the surface help get the snap reaction that I am looking for as opposed to the arc that I am currently getting? 3.)What are the differences between 4000, 2000, 1000, etc.? I would think that the higher the grit #, the more roll I would see and the lower the grit #, the faster the ball would start to hook? Maybe, I'm wrong...that's why I'm asking. Thanks for all the help!
