W000T: A buddy of mine says ping wedges are a tad slower than taylors.
It is possible but it depends on when the wedges were purchased.
When experience levels were introduced on Sept. 1st, 2010 the club swing speeds were tweaked to make them "easier to hit". The swing speeds were slowed down a tad on Sept. 1st.
The "old" Ping and TM wedges bought before 9/1 had identical swing speeds.
The "new" Ping and TM wedges bought on or after 9/1 also have identical swing speeds, but they are a tad slower than the "old" wedges. A tad = about 0.1 second.
Keep in mind, it is also true that a TM wedge bought after 9/1 will be slower than a Ping wedge bought before 9/1.
