You'll find that the sun sal will change with every release. Variety is good. BB41 with all of its variety was wonderful, but just as you loved it, many people found it overcomplicated and are preferring the more simple nature of BB42s track. The wide stances allow a different focus - besides, I'm sure that your instructor will happily go back and mix in your favourite for you at some point in the future...
No doubt Jackie will bring back a more varied SS track in a future release...
Go with the flow - and enjoy the journey
