The VTS is a fantastic attachment for your rack which adds a ton of variety for upper and lower body movements. It's incredibly well built, feels premium, and can handle all the weight you throw at it. Dialing in the rollers is tedious (check out MWPiG's setup video on Youtube to see what I mean) but makes the VTS pretty damn smooth for a roller-based trolley system. Performance-wise, it operates just as you'd expect from a smith machine and is actually quieter than most smith attachments.
Unfortunately, it's heavy by default though. With a standard 45lb barbell, you're looking at a starting weight of around 95lbs. With iso handles, you're looking at ~30-35lbs per handle. Swapping barbells/handles isn't difficult, but definitely inconvenient enough that I find myself not choosing movements that would require me to do so during my workouts. Value-wise, it's a premium attachment that I feel warrants the price tag; I find that it adds enough exercise variety to my home gym that makes it incredibly valuable. If I were only looking for barbell smith machine movements though, I'd look to the VTS Lite instead. I am skeptical about the hex port ecosystem because I haven't found that useful yet, but I'm hoping BPF releases compatible attachments that interest me in the future.
