I can't speak to the 86 TM but my experience with the 81TM is probably close because I'm having the same trouble, especially with long irons into wind. My distinct impression of the ball situation is that the Titleists are the new Nikes and the TMs are downgraded Nikes, specs notwithstanding.
Into wind the change is rather dramatic as these ball (81 TMs) seem to play like they're made of cotton. Headwinds knock them down something fierce and tail winds carry them a ton. These are the exact replacement for the Nikes I used to use and I'm having a bit of difficulty trusting them. Not complaining, just faced with a bit of a learniing twist.
For 100 credits more, no less. :-(
