Spoilers are of almost no use to a dedicated XC glider -spoilers will only reduce lift and add drag, while flaps allow you to increase lift with little drag penalty at lower deflections for thermalling, and of course larger flap deflections will provide a large increase in both lift and drag. At high flap settings, stall speed is reduced which helps with a slower, steeper landing approach which is helpful in an off field landing situation.
