I don't know that it really adds a huge amount to the "bling factor" compared to the nickel plated barbs you have. I just think it looks a little more professional and adds a little to ease of use since you never have to clean silicon off threads if you need to fiddle with the barbs. Also the quality of the rest of the block makes the goop look a lil out of place.
I also realize that digital cameras tend to really emphasize it (esp on the black Delrin top) more than if you see the block in person. And it's a minor detail for sure.
But I'm just sayin' is all
