Tire experiences from 300 to 200 TW

[DFRESH]

I noticed Nitto is making their Invo (in select sizes) with a 220 TW rating on them. Wondering if anyone has any experience (Track/Auto Cross) using these tires and how they perform as compared to a regular 300 TW tire.

I am seriously considering swaping out my worn out NT555's (the LR is especially bad as you know) as they are all getting close to needing replacement. How much difference is there going from a 300 NT555 to let's say a 200 TW NT05 in handling? Dramatic? Like a full second on a road course better?

Were shock adjustments necessary after going to a lower TW tire?

Weigh in---I know some of you have made the transformation.
