In my opinion, the Super K model doesn't even come close to the pre-1964 Kodiaks. Individual bow performance will vary of course, but my preference is for 1960, '58, '59, '63,'64, '62,'61,'54, and '57, in that order. 60" is nearly always better than 64". Not to pick a fight with anyone, because they're all at the top of the Bear heap, wrt beauty and performance. The '62 and the '60 are far and away the prettiest, as I see it.
You won't go far wrong with any of them.
