How it's formed3
All forms2
とすればtosurebaformal
味わうとすれば
ば swaps in for たら — stiffer and more written, at home in essays and reasoned argument; interchangeable with としたら in most contexts.
とするとtosurutoalternant
味わうとすると
shifts weight onto what follows as an automatic next step — "that being the case, then…". it reads even more like a logical chain than としたら／とすれば, though used the same way.
Notes
する marks a made-up scenario, なら picks up something already said.
