As a rule, if I change the slidertick hitsound, or add custom hitsounds to the slider tick, I mix in the default/custom slidertick sound as well so that any extra hitsound is simply extra, and does not replace the all important slider tick hitsound.
It's the same to me as switching hitnormal midway through the song, which is why a lot of moonfragrance's DJMAX songs, while awesome, do not play well for me. The removal of the snare hitnormal or hi hat hitnormal which I expect on every circle is removed suddenly, and it causes confusion.
Also, "tick rate" has nothing to do with hitsounds. I'm not 100% certain I know what the poll is about due to the language barrier.
