The ipv4 return-path to that first IP before your unlisted hop #1 goes through C&W, and seems to spike once C&W hands off to CPRM:

Maybe they have saturation on their peering/transit (whatever that connection is).
I can see if CPRM has peering information in EU and is at a mutual exchange. If you have any, we can try and use it.
Tracing to funet.fi from the tunnel-server seems pretty clean, so must be the overhead of that (possibly) saturated connection:
