Thanks Jazzy and Brian, I'm looking into those. Looks like Minotaur is based in Greece... there's a place not far from me that sells the Gruv Gear stuff as well.
I'm hoping to find one really nice strap to use on both my current Alembic and the future one in the works, but not sure if they'll balance the same or close being two different body styles, albeit with the same scale.
One is a Spoiler-body Persuader 5, the new one will be an Anniversary Omega 5-string. Measured from button to button, it probably won't be a huge difference... I'm just thinking the Omega shaped one may require a slightly shorter strap to hang equally. (because of the location of the lower strap button above the Omega cut)
Probably over-thinking things... but wider is definitely better with these basses. Neither is particularly light.
