Trevor, welcome to the hobby. I hope it proves exciting and fun for years to come!
That boom is purely for aesthetic purposes, other than a carbon fiber upgrade. I would stay away from the blade grips at all costs. more weight, more expensive, and form what ive heard, more problems. just get a regular carbon fiber boom, you'll be fine. And I'm not sure if this is the website, but i know a site was just repackaging dynam vortex parts and other parts and reselling them at a higher price. I think it was this site, dont quote me on that.
