Mark,
The decision to use ceiling tiles vs homosote was the cost factor. Our club president decided on ceiling tiles even though some of us have used homosote on our own layouts and it proves to be much more sturdier and track screws stay quite firmly into it. Bud and I were not happy with the cost decision to go with the tiles which are easier to cut but either way, they both still make some dust when cutting.
So far, we have used about 10 cases of ceiling tiles on the layout and probably need 2 more cases as what the nutty track professor aka Bud, claims.
Bud will say that I am the "nutty ceiling tile glue man" testing out its strength but he holds the "nutty track screws" title hands down!
