I'll go on record as saying I think the slider is a good idea. It's the subtle difference between picking from a pre-defined list at once versus exploring your feelings sequentially that makes it valuable. If as the weeks go on they change the wording so you don't always remember the answers it can be a way to consider each option without a bias towards another choice. If you see all options at once, you immediately compare them, if you view them sequentially you consider each one more independently. Perhaps this is a pointless distinction for some (and for some personalities I'm sure it is), but to me it's valuable to take time and process and explore my feelings, rather than choose as quickly as possible.
