Thanks, Treadigraph - I hadn't realised that the Tiger had evolved from another model.
My negativity mostly is received from others but I have to confess to not being a big fan of the DH82a and have often wondered why it was not improved in a way anticipating the SV4, for example - I never found it a particularly satisfying aircraft to fly. Dev Deverill once let me loose in The Deacon and I found that a bit disappointing too. Perhaps it's just that the DHC1 ruined me for other ab initio trainers.
I don't have Bunny Bramson's book - must buy a copy.
