That is fantastic! I have a soft spot for the SB-1! Best mallet ever IMHO (but the SB2 is nice too!)
The funny thing is I have over 20 putters and have never owned a center shafted mallet before. So far I'm putting the best with a center shafted mallet which makes me feel foolish that it took me 36 years to figure this out!! I will definitely be prowling eBay for another Seemore or two this year.
