Island greens should have the same OB rules as any other hole. I would always think that any island hole should have a significantly easier drop zone.
I don't disagree. But TDs haven't been following the design guideline passed down from ball golf which is to go to the drop zone immediately after missing from the tee. If they had been doing that and not brutalizing players, we might not have discovered an alternative. The proposed three shots then the drop zone is an improvement that produces better score distribution, and more opportunity to land a fun tee shot without being brutalized. This new option is allowed by our current rules under special conditions. It just hasn't been obvious.
