We study the homotopical rotation vectors and the homotopical rotation sets for the billiard flow on the unit flat torus with two disjoint and orthogonal toroidal (cylindrical) scatterers removed from it. The natural habitat for these objects is the infinite cone erected upon the Cantor set of all 'ends' of the hyperbolic group . An element of describes the direction in (the Cayley graph of) the group in which the considered trajectory escapes to infinity, whereas the height function of the cone gives us the average speed at which this escape takes place. The main results of this paper claim that the orbits can only escape to infinity at a speed not exceeding and, in any direction , the escape is feasible with any prescribed speed , . This means that the radial upper and lower bounds for the rotation set are actually pretty close to each other. Furthermore, we prove the convexity of the set of constructible rotation vectors, and that the set of rotation vectors of periodic orbits is dense in . We also provide effective lower and upper bounds for the topological entropy of the studied billiard flow.
