Depending from merged checkpoint performance and features may be different. For prompting you can use 4th tail style or just what you used to. Applied alignment allows almost any scizo prompts and it will look amazing but complex understanding may suffer. Autism is most flexible and closest to original, wai is the less but pretty, somewhere between them.

Merging scheme is simple: 4th + (model - pony) * (0.9..1.0), you can try other yourself to get best results.
