stevieb1, it's difficult to know whom (if anybody) to talk to in the corridor under the Solent CTA between Stoney Cross and the IOW.
Below 2000', you are under the Solent CTA and laterally outside the Bournemouth CTR. However, Bournemouth has the LARS so I think on balance EGHH APP on 119.475 is the more appropriate unit to contact. If the frequency is busy, a good second best would be to maintain a listening watch on that frequency, while squawking A7000 Mode C - you really can't do much else.
