Actually if you read the posts, a lot of people have good luck wiht Sprint chemistry and it get recommended a good bit.(posted 8679 days ago)Why do some people still mix powdered D-76? Because they are used to it. Because Sprint is not stocked locally. Because they have a LOT of D-76 still around. Because they like the space savings of D-76 for storage when they don't use it often.
As to their stop, I know it is odorless, but not sure what they use. "The Film Developing Cookbook" suggests that citric acid NOT be used as a substitute acid stop. THey suggest that this is not good with current emulsions. They recommend boric acid or the old stand by, acetic acid.
As to their Rapid Fixer, I was going to get their's the last buy, but the shop was out, so I got Kodak instead. Maybe next time.
WRT hypo clear, I use Heico PermaWash. It tends to get highly recommended by a lot of serious darkroom workers.
