Yeah, just echoing what Jester said; we have the Blue Bowser's Alt on our scene's custom build and people definitely prefer it over the original since I have heard complaints about that. But Blue Bowser's is a godsend since the air isn't any color now. I definitely suggest other scenes that run Bowser's to have a custom build optional for people to have w/ Blue Bowser's as a choice.
Here's Nebraska's custom build: https://drive.google.com/file/d/0B8dchbDGV0gobkdxdDRQb2pKdjg/view?pageId=103592611551531803611
