Query: Staking system weaker than the one I bought earlier

This is the second staking system that I have bought for my Earth Boxes. The design has changed by eliminating a metal rod in the middle. Thus, the staking is weaker than the first system that I bought. Part of the problem (if you can call it a problem) is that my tomatoes grow so tall in the Earth boxes that I need a sturdier staking system.
