Record Weight?

[Formerly YB-2]

What record weight/clamp are you using?
I'm currently using a Stillpoints LS1v2 and it is the only record weight that I've used that has actually made a difference. All my pre-LS1 record weights worked well enough, but if put in a box and picked out blind I would not be able to tell the difference, one to the next. While a plus compared to no weight, they were all pretty much the same, SQ-wise. Not so the LS1. Truly worth the $$.
Which brings me to the reason for this post. Has anyone tried the HRS record weight? Am guessing it is at least as expensive as the LS1 and am wondering how it sounds compared to the LS1. Any experience with the HRS out there?
