which ones are you talking about? think you have it backwards because SS is a bit higher, however If you use the ss code, you get a discount.
I have heard good things about RUI and I am sure sponsors or member will vouch for that brand. I personally have not used RUI. I am running SS LG now and happy so far.
regardless of which way one was to go, when you search the web for reliable sources Sarmssearch and RUI have most of the positive feedback from consumers. that alone is worth its weight in gold.
