I also found Tucker Deeter listed and endorsed by Kirk. I got a quote for the usual 1 million/100,000 liability with 25K hull for $365.00, also saw what you had written about "soft coverage", may change to that
aopa quoted me $483.00 for 20K hull
I had insurance with Tucker Deeter (Wenk Aviation Insurance) from 2014 til now. With Wenk, I paid $540/year for a $25K hull/$1M smooth limit. AOPA charged me $730 for the same coverage.
Even though I sold my plane a week ago, I chose to keep the policy in force until it expires in mid-March. That way, I have some "After Sale" coverage in case some maintenance work that I did causes the plane to crash.
