It all boils down to the adage I heard from my Harley mechanic when I wanted
to take my new Twin Cam motor apart after it was only 3 months old for
bigger pistons, cam, timing, etc.  He asked me "How fast do you want to go?,
then he asked me, "How much money you got?"  Speed = money, money = speed.

60 Sprite (not too fast, I don't have that much money)
56 BN2 (not fast, but a lot of money anyway)
