In the last three years I have tried the triangle stakes they sell with tubes (expensive but good), driveway stakes (too short for me), a few metal options (too rigid, short and/or expensive), bamboo/wood (not bad but short life), pvc (good with minor work to cut) and those green "garden" stakes that look strong but are hollow (save your money please). Unless something else catchesy eye to try, I will stick with cutting pvc to length.
