I haven't been through that VOR-VOR corridor under Stansted yet, but I'd thought simply following the A10 from Royston - M25 junction (remembering to duck under the 1500 zone) would be safer - much better visual clues and avoids everyone else who will be using the beacons.
I'd also have thought it was safer than tracking the VORs - personally, I'd be wary of relying on using VORs as turning points unless equipped with a DME.
Just my two'penneth worth anyway.....
