another solution could be to stay as long as possible in poly. as subd is only the endresult after smoothing. so you make the best possible version you can do in poly and go to subd in the last step, adding some creases to the model. if you model good in poly you wont need to pull any subd vertices. but be sure to only create 4 vertice polygons. if you use anything else, you slow down the subd an awefull lot.

some technical thing: i believe (i am not sure) that the subds in maya are subdivision NURBS surfaces - as they behave exactly as subdivision b-splines (algorithm wise from what it looks like). and these subdivision NURBS surfaces can be calculated real easy with 4 vert polys, and have a huge overhead then you have other polys (this could explain why maya gets slow if you dont use 4 vert polys).

hope that helps
