[QUOTE="Reelamin, post: 2350159, member: 42157"] Hmmm I have a totally different recollection of why tops spun longer or faster 50 years ago. None of it had to do with barrel twist rate. It only had to do with how fast you got it spinning by the length of cord and the weight of the top. I have some shooting to do, but I will research the heck out of this. Could you hook another old brother up and search the internet for some mathmatical/scientific data to support an item will spin faster or slower because it is pushed down a set spin rate faster or slower. I have only seen videos where they used gel and used two different twist rate barrels.....and proved the claim wrong and can accept that is only one test of a theory. [/QUOTE]
