I've found the stock LG really stiff and the curved shape promotes transfering a lot of landing shock and load directly to the fuselage. Even a simi-hard landing will cause damage to the fuselage skin and LG support structure. A somewhat expensive fix is to replace the stock gear with a Bolly or similar shape gear that has a lot more flex than the stock gear. It will absorbe most ot the normal landing shock rather than transfer all the load directly to the fuselage.
