However, I had never considered skipping logically required Talent prereqs (Spinning Strikes without TWF) and I agree that those should not be allowed (but probably would be per the current errata).
As the attack penalties for Spinning Strikes still follow the TWF rules, using it without the TWF Talent is a *really* bad idea. -2/-2 vs -3/-4 (although looking at it, there is little difference if you fight with two non-light weapons, so I can see the occasional use for the combination without the Talent).
