Those Alps switches are among the more heavy and tactile switches out there, I'm not sure where you should go from there. The general consensus is that the buckling spring boards, like the IBM Model M and the Unicomp boards have a heavier feel… I have 2 of the Ms, but haven't really tried any other mech. boards to compare. The black cherries are heavy, but not tactile, the other boards are all lighter, from what I've heard.
