Given the X20 has a PVR of 4, I'd expect whichever one of these two doesn't end up at Blyth will end up at Ashington as the X20 spare rather than stretching the already low MAX spares at Ashington.
Actually, one B7 spare at Ashington makes sense as MAX spares 7515/7516 are from 2009 (at least 6 years older). These already see service as Sapphire back-up vehicles, Summer extras, extra Match capacity never mind spares for the X14/5/8!
