Proper thinset depth and coverage is critical to any tile install, and maybe more so when you use a clip of some sort. A curve on the bottom of the clip may work best since there would be thinset around most of it, minimizing plastic to tile or substrate contact under the tile. But, of those I've looked into, they require moderately deep thinset coverage, which is not unusual for a bigger tile (and the ones these things work best for and are recommended for).
