Hey everyone,

So I`ve seen a lot of people using the Rupes LHR21 with a 5 inch backing plate and some say it works great. Others say it`s a little unbalanced compared to what the rupes usually is. If the 5inch backing plate works on the 21, shouldn`t the 6inch backing plate work on the 15? Curious on if anyone has tried the 15 with a 6inch backing plate and their thoughts?

I know the 21 is the most popular, but I`m just a weekend warrior and don`t do a lot of heavy correction. I usually use 5.5 and 6.25 inch pads.

Thanks,
