^exactly that.
In singles, I NEVER use Fthrow if they do not tech the Dthrow. IMO: a grounded tech chase is 100% safe vs Fthrow you have a lot of variables and none are 100% safe. In both cases, you have the advantage, Dthrow being more adventageous however.
Of course low % Uthrow<Uair strings/baits, BThrow anytime to get them offstage (always a positional advantage), and dthrow at mid percentages for potential tech chases. Fthrow in dbls or if they consistently tech Dthrow and I need to save Uthrow for some reason
These are just my personal preferences though. Works for my playstyle
