The only hard bit then is flying an AH failure if it occurs....
And believe me that is deadly serious if it happens at night and/or IMC. If you are flying aircraft with only one artificial horizon installed then you have a flying time bomb. While switching to a turn-coordinator is your only solution, it takes currency and a lot of pure instrument flying skill. A two minute "practice" on limited panel once a year during the annual instrument rating test in VMC does not make you current.
A wise IFR pilot will ensure he he keeps current on limited panel (no AH) flight by hiring a synthetic trainer for an hour of limited panel practice several times a year. And for the cost conscious, it is a valid tax deduction.
