I may be alone in this, but I just made Legend a few hours ago, and don't find it that much harder than TM. I'm already used to the wind and 12-stimp greens from playing lots of tourneys while working through TM -- not that I have them handled, mind you. So, it's only the added length that's new for me.
I'm playing L8x gear with L33 Cally balls, and have a 65 at PB (32/33, practice), a 34 at Oly (practice, B9), and a tourney 35 at Oly. Not the low 60's OP was mentioning, but in every case, they could have been. My downfall was making silly mistakes (badly missed ding, choked on an easy putt, wrong putting scale, etc).
Now, time to practice, practice, practice... (There's a theme here. :-)
