I have the Aggro 2x which I think has perfect aggressive knurl. It's great for SBD but I usually pick a less aggressive bar when doing low bar squats because the Aggro will chew up my shoulders like no other. If you want a premium bar with aggressive knurl, the 2x is excellent. If you're a sadist, go ahead and grab the 3x.

Best Mag Pins on the market in my opinion. Magnet is the perfect strength and the grooved head makes these the easiest to move.

Best option out there for change plate storage, especially because other brands will require 2 holes on your upright and Horn Hub only uses 1. I 100% unnecessarily sold my Sorinex change plate storage and bought these, just for the love of the game and Darko products.

Best EZ Curl bar I've ever used. Diameter is thick, knurl is perfect, and it's shockingly light. It's expensive so the value proposition won't make sense for everyone, but if you want the best of the best, this is it.

Pros: Great build quality, awesome angles. Cons: Bearing most likely needs lubricated periodically, unnecessarily heavy.

The Ibex is incredibly underrated and is a damn near perfect functional trainer solution for home gyms. The form factor is sleek and compact, so the weight trolleys and cable carriages take up minimal space on your rack. The pulleys and cables are routed smartly and precisely so that they don't add unwanted bulk to your rack and stay out of the way of your other attachments. The Ibex is unbelievably smooth, much better than other plate loaded cable machines AND many selectorized units that I've used. The real sauce is in the cable retractors though! These allow you to unlock and pull out as much cable length as you need, then lock the retractor and engage the weight trolley at your preferred position by letting the cable retract to engage the weight. This means you can get into position with no tension on the cable before starting your movement. This is insanely useful for movements like seated cable press, overhead triceps extensions, and chest supported rows. I can't recommend the DM cable systems enough, especially the Ibex.

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.

This is probably the best EZ curl cable attachment at its price point. Rotates smoothly, looks/feels nice and gets the job done. Speaking on performance though, I think the knurl is too passive, the diameter is too thin, and the angles aren't sharp enough; I ultimately got rid of this and upgraded to a more premium option
