By "Tiger"I take it you mean AA5, not the DH82A variety.
Anyway the route sounds good with one (minor) change. OCK DCT
SAM N866 EGJJ.
Intially you'll work Thames RADAR (132.7) then probably Farnborough (125.25). Remember to ASK for your joining clearance ASAP. Depending on the situation in TC (OCK) sector you'll either get a joining clearance and told to contact 134.12 or advised to request a join from Southampton 120.22. Either way you'll end up working Sector 21 at LACC 129.42.
Hope this helps
