Sorry about the misinformation about the box finishes... i was just trying to say that they both have smooth finished surfaces, using abralon abrasive and no shine on the cover.
Also, there is a difference between high performance products and upper-mid performance products... if it wasn't the case then why would they sell different products at different price points. Higher price points usually have lower RG and higher Diff, where as upper-mid might still have low RG but a little lower Diff...
Anyways, thats my take on things, like i said... i really think the Rival would be a great addition to your arsenal and it should fit nicely under your Infinite One.
