I want to change my wooden riflestock for a good, composite one.

I tend towards a B&C Medalist with a FLBB.
Would this be a good decision accuracy wise or would it be better to take one without the FLBB and do a proper custom bedding job?

The bedding blocks are great for a stable and stiff platform, but they still need to be glass bedded.

Neither the aluminum, nor the receiver can be machined accurately enough to match one another the way a glass bedding job will do, despite the marketing to the contrary.
