Replying to Could a ski company help me out..

I am in the process of building a pneumatic press for skis at my school. We are making the cores inhouse and getting the profile with our CNC machine. If you could help with core composition as in which species of wood work the best for a pow, park, and all mountain ski. Also the process in pressing skis would help too. In the context of order and timing of pressing epoxying and how to do edges. One last thing would be how to make topsheets. Any help would be highly appreciated.
