HA! My advice is to get over the red mark, hahahaha. Be tough girl!
DBs would be harder if you used a comparable load to what you had on the barbell. The barbell allows you to brace your hands laterally against the bar, so it's more stable. DBs require stability to be created in all directions. That's the reason most people (not all) can barbell bench more than they can DB bench and barbell OH press more than they can DB OH press.
With all that said, I wouldn't think it'd make the movement any less metabolically challenging if you can use sufficiently heavy DBs. So if you want to use DBs, go for it. The point of the movement is its metabolic cost, not solely learning a new barbell movement.
