That's easy: my solution is the best! :-)
just kidding.
1. resources: if you had NT you could use the task manager to find the true resource usage without guessing.
I doubt, though, that resources should be a real concern.
2. that's not really a "large" size. all 3 approaches can handle that easily
3. use the text box approach and be totally independent of the smartness of the underlying grid
4. see 3
5. that's not a problem of the grids.
