i am thinking of having my killer instinct sanded polished and i wanted to know how well it would hook if i did

If you already have the Big Blue Pearl, why would you want to polish the Killer Instinct and make it very close to what you already have?  I'd leave it dull, so it's ready for oil if you see it.

I never said they would be the same.  I was just trying to keep another bowler from buying strong equipment and shining the heck out of it trying to make work on less oil.  Too many bowler's bags have 4-6 hook monsters shined to the hilt.  Unless they are bowling on challenging conditions, there is rarely 5 boards difference between them.  Shining a KI would probably give a little different look than a BBP, but enough to justify carrying both?  Hard to tell.  Then again, you can always easily dull it again, so it would be harmless to experiment.  But if you ever hit oil, you're going to want something with some surface.
