which is better triplus or rapidus?

Does anyone have a screenshot or can verify that once you proc TH7 w/hands, knife, feet then replace knife and hands that it procs to 8+.

Yes. And as Laphine mentioned is very easy to test for yourself. Land first hit with full, TH gear. Swap to DD gear. See the next proc go to the next highest level.

Idk about pics, but this is accepted because everyone can check this behavior (and it's easy to do so). The tricky thing is whether wearing TH+ gear while tping increases the odds of a boost happening. Ppl discussed this idea on this very thread. But it's not easy to answer this question, because it would need a very long and well controlled test.
