As an application, we construct infinitely many contact structures on the class of simply connected contact manifolds that admit nice contact forms (i.e. no Reeb orbits of degree -1,0 or 1) and have index positivity with trivial first Chern class.20 pages; corrected typos, added some explanations in section 2.3; to appear in Forum MathematicumSymplectic Geometry53D10text
