Whats the best way to gain flying hours to get an ag pilot job?

-I am a private pilot and am planning on going to an aerial application school to become a cropduster next year. I was wondering if the best way to gain hours in a taildragger for insurance purposes was to buy a small taildragger or to rent one. Any info about any of the following would be great. Thanks.If you can afford to buy one, do so. If you cannot, rent as many hours as you can. Either way the name of the game is being insurable and total tailwheel time is very important. You need a high level of tailwheel proficiency, particularly operating at max gross weight out of small, mostly unpaved airstrips and in crosswind conditions. It would help if you could work a season as a loader and flagger for an ag operation so you can "learn the ropes".
