This ball looks good. There are 2 videos on YouTube. I'm having a hard time picking between this and the GB2.

From looking at the specs, it looks like the core is the same just the numbers modified with the lighter weight

I've never known the 'early Christmas present' idea to work.  I got in trouble anyway.  Maybe put some of that pink Columbia 300 thumb tape in a box for Christmas just to cover yourself.

I threw mine tonight for a couple of games on breakdown of a 45' pattern, and it matched up really well, didn't overreact to the dry even with the polish.  Without the polish, I think it will look great on medium length/volume patterns, but I'll try that out before I say that definitively.

As for stronger reacting pearls...you could throw some polish on the TakeDown, that's a pretty strong pearl that has surface out of box.  The Crazy Antics covers some boards in the backend if you're looking for a pearl asymmetric.  For me, the Blur Pearl isn't enough ball on lots of volume, whereas the Crazy is, and if you want to define pearl by reaction shape, you could say the N'Sane rolls like a pearl even though it is a solid. 

So I guess after that ramble by me.... I think it's too early to look for a Vow replacement.  If C300 did that they'd have to increase the number of releases to accommodate all of the product choices.  Maybe to start 2015?

I'd prefer that they put out quality balls, rather than over saturating the market with random and half a** attempts at bowling balls.

I'm not sure which Columbia balls you're referring to. The Eruption Pro and the Disorder are as good as any balls in the market within their respective categories. I just picked up the Nsane Antics. I've only thrown a few practice games with it, but I can already tell it's going to see a lot of action. 
 
I'm not a Columbia homer by any stretch. I mostly have a mixed Storm/Motiv arsenal, but the Columbia balls I have are every bit as good. I'd rather the colors were more basic, but I'm more concerned with performance. Many Columbia balls deliver.

The Throwdown is going to be a great piece! The colors are awesome (Yeah, I like colorful bowling balls. So what? hehe) and this is definitely the cleanest ball of the three in the line. I, like my teammate above, don't find the ball to be uncontrollable, but it definitely packs some bang for the proverbial buck!
