It's unfortunate that the Barley/Fantini/Penny Cooper team inscribed the grades at the base of the three aforementioned routes because they are great additions to a previously undeveloped part of Euglah.
As for the other new/newish routes at Euglah, I've done all bar Fantinis Edge of Ecstasy, next to Edge Effects and the only route that needs chopping is the arete next to Clampdown. Don't know who bolted that (was not Barley) but it seriously impinges upon Clampdown, a v thrilling climb in the past but sadly not now.
Sadly thrilling bold memorable routes are becoming a rare species. I'm just glad I got experiences like The Plunge (Piddo) done before it became just another clip up. Totally Unforgettable v Totally forgettable. Lost forever and lost to future generations of trad bold aspirants.
