hi mike,
Taylor purchased their first Fadal CNC in late 89 & all guitars up until that point
were 'hand-made', with a good bit of variance in neck carves & other areas
the NT neck was phased in beginning in 99 & thru 00 & with the CNC process
continuing to be refined & more exacting, there are many that feel the preNT
neck Taylors have a slimmer, 'faster' feel, regarding the neck carve/profile
Taylor currently offers several different neck profiles & i believe that
the slim carve is meant to be quite close in feel to the older necks
