  We study the continuum limit of adjoint SU(2) LGT by means of a suppression
term for Z2 monopoles. High barriers for tunnelling among different twist
sectors are overcome through parallel tempering. Monopole condensation is used
to study the deconfinement transition and the properties of the confined phase.
Ergodicity in summing over all twist sectors allows an unbiased measure of the
't Hooft vortices free energy. Its behaviour in the SO(3) confined phase hints
at differences from what conjectured for semi-integer discretizations.
