I am glad we have both discovered the Silver Lace, Hiflyer. I will start a thread on them in the Sound Advice category very soon. Please make sure to post your impressions. I discussed the RFI blockers in another thread, please check it out as others have comments as well. In short, I think if you need them, use them. If you have no RFI problems, I would forego them. Someone sent me the ones I am using so I am no expert in this area. Sorry about that.
