Roger,

I don't have a IV, however I have flown out of a 1000' grass strip with my 7 and I know full well there would be conditions ( wind etc) that can occur where I would not use the same strip.

A 7 is not a IV, however, I do agree with Av8r3400 100%.

I didn't even try the 1000' strip until I had a lot of practice on long strips and was certain I could operate within that distance without memorializing the situation in ways a person wants to avoid.

Sincerely,
