Hi all, I installed Morpheus' Boogie Men arms in my SS last weekend. They work great so far! I haven't had much time for pinball lately, so I don't have 100 plays on them yet, but here's my initial thoughts:

* They're very light. I was worried they might affect sling action, but they don't at all.
* I was warned by a friend that these arms can damage the SS sling plastics. There's enough play in the arm that it CAN technically touch the sling plastic... I won't lie; I'm nervous about the plastics. But I see no issue right now.
* Install was simple. I had to remove the linchpins, remove the sling pivot bracket, and take the sling plastics off to swap the brackets. It took maybe 30 minutes total.
* Morpheus gave me some Boogie Men with the arms. They're the nice flexible ones, not the stiff plastic style, so they dance a lot!

The kids think the Boogie Men are hilarious, and now bug me to play Boogie Men mode, is screwing up my scores.

Thanks for the Boogie Men arms, Morpheus!
