110 gear inches is plenty for most people. Jan is a stronger rider than 99% of people, and he claims he has never been dropped on a descent due to not having a high enough gear, and his top gear is 90 gear inches. 48x14. By my reckoning you lost nothing by losing your 123 inch gear. You discarded the correct part of your gear chart, IMO.
