The Orbest A320 operating on behalf of TCX did indeed go ABZ-TFS direct.
TOM also operate ABZ-TFS direct with their 738's however I believe they are equipped with slightly more powerful engines than the Travel Service ones (27k v 26/24k) which seems to necessitate the fuel stop at MAN. A320's also have nice and powerful engines as well.
It's unlikely that an aircraft will be at its MTOW operating (trying) out of ABZ. It may be full of passengers but not at its maximum take off weight.
AnywhereButAbz - ABZ could have a 5000m runway but it would be no guarantee of long haul because the demand (or infrastructure besides the runway) just isn't there right now to support regular scheduled widebody ops.
