One thing I really think I suffer from and would like to minimize is throwaway. Can the 10-2-D grip make throwaway more likely to occur?

If anything Michael, having a 10-2-D makes it harder to have improper impact alignments.
For my students with chronic throwaway problems, I always assign them some quality time chipping with a 10-2-D grip followed by a cross handed (10-1-E: strong right hand action cannot overpower the flat left wrist) grip.
Once mastered, impact fallout is almost impossible!
