Dear Doctor,
Strictly speaking I have overcome the problem of wrist angle by cleverly attaching a protractor to my wrist with a very neat harness contraption I fashioned from an old truss and surgical appliance of yours that Cabo kindly sent to me. I don't know how he came by them as I thought it best not to ask.
The problem now is that the protractor keeps catching on the strings. I've changed my bridge twenty-seven times in the last four days, have six inches of shim on the bass side and have changed to a hand carved by Trappist monk 12mm pick made from crystallised unicorn shit, all to no avail. You are my only hope.
Yours etc etc............
