That sounds right to me. I'm using the felt wedges sold for bass tuning. Wide ones mostly but the thinner ones for uprights until I run out of room. The Papps mute is the plastic chopstick thingy with a spring to keep the tips apart? I have one in my kit, but have not really tried it...I'll give it a go on an upright this afternoon...
