Thats a long long list... do you usually only read once or twice with a reader @Love2lovenj?
I tend to read with just 3 or 4 readers at max, for a long period of time... at least 6 months.
Every reader has strengths and weaknesses, when you read with them regularly, you understand better how "their messages/ views" apply to your situation.
What are the advantages that you found with reading with so many different advisors?
