I used Lo Rider Stainless on the RA that I had and they sounded killer. To my ear, they are quite similar to the Sadowsky Blue Label stainless.... relatively stiff tension, and lots of upper mid grind versus the low mid growl of the Lo Rider Nickels (which fit my LG much better... but again, as you mention, my LG is more typical of that spec versus yours, which has a bit more aggression to it), and the Lo Riders move that treble sizzle of the Hi Beams down to the grind upper mid/lower treble area, which works a bit better with a RW board than the 'scoop' of the Hi Beams.
The Lo Rider Steels also helped the kind of tame that 'scoop and upper treble click' that my RA had... made it more growly and grindy all at the same time... nice! My RA with Lo Rider Steels sounded a bit closer to my LM with Hi Beams.
I bet that sounds killer from what I remember about your particular LG!
Your LM is looking MASSIVELY KILLER
