Kumba, as OF stated, was painted fairly recently. Kumba was the world's first B&M Sitting Coaster so it shouldn't be converted to floorless IMO. Besides, when they converted SheiKra to being floorless, they had tons of issues, and still do to this day. Not sure what it is about B&M Sitters but between Kumba and Hulk they tend to be more rough than others. Maybe they could do something.
