I feel that a switch double bio would be easier than a regular one, just because of the positioning of the body. you are forcing yourself in a different kind of spin when you are popping off switch, rather than flowing with the spin more. You'd be able to set it better IMO. but I can't really talk, I still have to throw a dub this year and stick bios before I can understand it fully.
True double bio would be hard as hell. u would have to huck super hard but be only doing a first bio then come up again and huck another small bio. and is it just me or have you never seen a bio smaller then a 7? Now like a double dipped bio would be more practical like if u went for a bio 9 and at 5 or so dropped your shoulder again and just went into more of a bio.
