Those Avons are used by many Morgan Competitors, because they give exceptional grip in both wet and dry conditions.
Dave and I have discussed this on another thread, it may be the conditions he found were exceptionally testing for a tyre with minimal tread, pattern and therefore limited ability to clear deep water BUT under all other conditions they are superb. In the dry they will hang on for ever, you will run out of brakes before you run out of grip. On a "normal" wet road they are also excellent and you won't need to slow down too much from your dry speeds (but please remember you have no abs in a Trad Mog and therefore should use cadence braking)
You do need to scrub them in well before using them in anger (like a track day) but once ready they will give great performance . Don't worry about warming them up, they are a very soft compound and will start to respond well from the outset.
Apart from deep water clearance the only real downside is the price.
