I purchased the Heavy Duty Pad recently for the riot safety squat bar. I found whilst using the original pads that they could fall off easily and generally felt very thin especially on the upper back / neck. So far I've worked through two squat sessions using the heavy duty pad and the difference is massive. The main thing is the pad is now a single unit and not 3 seperate small pads. It makes the safety squat bar feel much better and far more stable now on my upper back. It also means that we can now do JM presses with the handles taken off if you so wish. I recommend upgrading your riot SS bar with the heavy duty pad if you have the money to do so. I'll keep the original pads in case I ever need to use them again but I highly doubt I will need to as this feels like it's very well built.
