I got two questions about Dannie with Saber.

First question: does he prefer speedtuned or base speed saber? The saber team I've been planning on using is saber, Dannie, Sunday, and robin. Right now, there are two builds I can use for saber and Sunday specifically. Saber would be 132 speed, while Sunday would be 129, and the other would be saber at base speed with Sunday at 150+ speed. Which one would be better for Dan Heng, who he himself is at a speed of 155?

Second question: how much better is 2pc banana for saber as opposed to salsotto? I have very bad substat luck for banana while salsotto is very good, so can I just keep using salsotto or is the difference just too great? Also, is banana worth grinding of I already have a decent salsotto set?

Any help would be appreciated! Thank you!
