I used the TM's when they became available to me, and made Legend shortly thereafter. Around 6 months later, after I began having swing timing issues I went back to the lvl 80+ Nikes which are the same irons as the lvl 85 Callys, only with a 4.0 meter instead of the Cally 4.2 meter.
If you are comfortable with the 4.0 meter of your L47 Nikes, the TM's with a 3.0 may be too fast. When I leveled up to lvl97 I had a free rental on the lvl97 callys. They played the same as my lvl 92 Nikes, except with a 4.2 meter.
So I would guess that that applies to the lvl85's.
Hope this helps.
EDIT:
The attributes of the TM's are better, they will stick the greens better with a decent spin ball compared to the Nikes. But the difference between 3.0 and 4.2 meter speed is really big.
And congrats on making Legend. As you are finding out it's a different game now.
Good Luck,
