Whether or not to keep using Hyotekis past level 10 is a situational and personal decision.

If you want your subs to tank, you'll obviously want Turbines on them instead of anything else, maybe a Repair if you have good reasons.

If you want reliable day-time damage, Hyotekis work well if you don't have a large stash of Quintuples, which most people don't have (Let's not even mention the 53s.).

If you want true sinking power, go for standard torpedoes, even the Triple ones will likely fare better than a set of Hyotekis during night battles. My level 75 subs can blast 2-3's Elite BB boss for 200-250 damage with a cut-in, which has roughly 50% chance of triggering.
