Hi Greg,(posted 9030 days ago)If I understand right, you want to process different films in Xtol at the same time. Sorry, it doesn't work that way. The Kodak times are close, if not perfect, for your needs, and that's just the way the different films process. Worse, the T-grain films are fairly sensitive to development. You should stick close to whatever time you zero in on as optimum. IMHO, any of these films will give excellent results in Xtol, if processed to the contrast index you require. Which one is best for your dance photos, only the test will tell!
