I had the Big One, threw a friends TNV, and recently purchased a NVS.... This doesn't make me an expert by any means....but I did stay at a Holiday Inn Express once.
From what I seen the NVS fits right between them but is closer to the Big One.... The Big One hooks up earlier than NVS and hits pretty good.... The TNV seemed to go longer in than the NVS and hit a ton, it was brought to a 2000 finsh..... The NVS hits a ton. OOB finish will work really well on drier lanes, if their is a ton of oil hit it with 1000 abralon pad. Just by hand, you don't need a spinner. I am going to try this with the cover and see, dry-medium out of box (2000-polished), medium-medium heavy (2000-dull), heavy oil (1000). My house shot is typically med-heavy so I have taken a 2000 pad to it and it's great, except for the new blister on my thumb (wrong insert size and weight change).
