    I have yet to see any other product on the market designed to be so tailored to personalization. The big stack is plenty sturdy to handle high weights and is easily stackable. Overall a robust and impressively customizable product to fit any archers needs

    As someone who uses a 1″ extension, it’s definitely 1″ in length and it’s plenty sturdy for high mass weight. No doubt it does what it’s advertised to do!

    I must say I am very impressed with Big Stack. It’s cool to play with the length of your extension without putting out a ton of cash for multiple products. I am using these with students to help them figure out how they want their setups to feel. The Big Stack is quite ingenious!
