Oh it must be so difficult for you. I can only sympathise. How dare those liberty taking red watchers not turn up for duty when they're unfit. If only they could be real men like everyone else.
To answer the original question. FL100 southbound in that vicinity isn't ideal. There is a standing agreement for EGHH/EGHI northbounds in place climbing to FL100 towards NORRY. A lot of controllers will keep you at FL90 until clear of any Solent outbounds.
What is likely to happen if it is anything other than dead traffic wise is you will be given clearance to join CAS o/t WCO, then given vectors in a south westerly direction to intercept L9 in the vicinity of KENET. This will keep you clear of any TMA departures and will get you "out of the way" sooner. It's also a shortcut!
The situation in this section of airspace can vary enormously depending on which aircraft are going where. A gaggle of Solent inbounds, an EGTK inbound, an inbound on a base leg to to EGGW on 08, or anything else that may end up out that direction may make the controllers plan very different.
