I also use Christine to insure Destiny & DunIT. They are insured for reasonable amounts on mortality and have $7,500 of major medical each. It's just under $1,000/year. It gives me a lot of peace of mind.
We too use GenCorp and our contact is Christine Phillips. I think we have 5 or 6 horses insured with them currently and they have been great to deal with and the rates are reasonable.
