The BOS Weight Stack Pin is not as heavy-duty as the Gympin version. But it is also around half the price and fits perfectly on BOS Selectorized Cable Tower. It also comes with a cotter pin to secure the weight pin to the stack and a weight collar to keep the weights on the pin. I personally don’t like the weight collar since it is a spring-style collar that requires a little extra work to place and remove. I prefer to use a clamp-style collar, but it is still nice that they include these extras with the pin. The weight rating is only 20 lbs, but I am mostly using the pin for micro loading weights, so that is fine for me. Also, I noticed that if you load too much weight on the pin, it moves the center rod on the Cable Tower off slightly so that it starts to scrape against the back inside part of the selectorized weight plates. I think that getting a Gympin loaded with extra weight might exacerbate this issue. Overall, this pin is a great choice for the BOS Cable Tower at a great price!

I think the UPS High is underrated for smaller spaces. I have a smaller gym space with a four-post power rack next to the back wall. Adding a standard lat pulldown attachment to the back of my rack would have required moving the rack out more, which would have meant less floor space for me. The UPS High allows me to have a rack attached lat pulldown coming off the side of my rack. I use a Bells of Steel leg roller to hold my legs down. I can bench and then sit up and go right into a lat pulldown. It’s expensive for what it is, and having to deal with a loading pin can be cumbersome. But it works really well. I bought a Bells of Steel cable tower and modded it for pulldowns, and I keep going back to my UPS High for any heavy lat pulldown movements because it feels superior.

I can understand why people don’t like this bar. Yes, the knurling is too passive. Yes, the curve is a little weird, and the bar can flip on you if you are not careful when loading the weights initially. Yes, there are far better options out there if you have the money to spend. But I was able to get this bar for about $250 new. This was at a time when I was having trouble squatting with a regular barbell because of shoulder issues and I was concerned I would not be able to continue squatting. I have been squatting with this bar for the past few years and have been able to squat over 400 lbs without issue. I do find it a little awkward for pressing movements, but I think it works well for squats. For loading, I have a couple of 15 lb bumper plates that I put on first before loading the 45s. So long as I do that, I have not had issues with the bar flipping. Down the line, I may try to get a better curved squat bar. But if you can get this for a good price and are aware of the shortcomings, I think it would still be worth considering.
