What's the best trellis for indeterminate tomatoes?

Specialist-community consensus on r/vegetablegardening is consistent: cheap, short cone cages are routinely 'too small' for indeterminate tomatoes that grow past 5-6 feet. Reviewers favor taller adjustable stakes (like the 68-inch K-Brands system) or sturdy flat metal grid panels staked into the ground, and several note that anything over about 6 feet of fruit-laden plant needs extra anchoring to avoid tipping in soft soil.
