Outriggers on Verity Audio Parsifals?

I recently bought a pair of Verity Parsifal Encores and I'm thinking about putting outriggers on them. The bottom cabinets are 52 pounds heavy and 10.3 inches wide by 23.5 inches tall...without the monitors on them (that adds another 14 inches or so).

I once had outriggers on a pair of Von Schweikert 4Sr's. I liked the added stability. Experiences? Opinions?

Thanks!
