IIRC, when the v3 silvia came out, they were all multi-hole steam tips. Customers complained, and Rancilio responded with a single-hole tip. Could have been a Silvia-specific issue though.
Although I've never used a multi-hole steam tip, my understanding is that while the multi-hole is easier to use initially, the single hole is better with a little practice.
