The Twin Stack is Rogue's answer to the Rep Ares. It features two side-mounted weight stacks and four pull points. The two functional trainer trolleys offer 2:1 resistance with independent pull from each stack. The high and low pulleys are effectively 1:1 by pulling 2:1 from each stack and combining the feel weight. That means you can pull up to 150 lbs per side and up to 300 lbs for lat pulldowns and low rows. The trolleys glide up and down the uprights smoothly on rollers, but do require two hands to grab both handles and to easily engage the trigger-based pop pins. The oversized pulleys mean you get smooth operation from every pull point. The optional shrouds aren't really worth the cost. They look great, but can get in the way of using stack attachments like a gym pin and force you to use the spacers on the weight storage. When the Twin Stack was first released it was priced almost identically to the Rep Ares. After several increases it's hard to recommend the Twin Stack on a value basis. If high build quality and made-in-USA is worth a premium to you, then the Twin Stack is still a great buy.
