Hi, Steve,
As a true ST 46 fan, I reluctantly suggest that the new Double Star 54 is "better" than my best ST 46! Outstanding run character, nice, controlled power, excellent 4/2/4 break, VERY user friendly. Several of us in New England are running the DS 54, with very good results. Highly recommended! Note: this is the NEW ball bearing version, not the older DS 50. Parts are readily available, etc.
