And even then, if you do switch over to PS, you can save the files to .tiff yourself to reduce the size of the files.

I used to only save .psd because if the .tiff file is saved correctly to reduce size, PSPx2 wont show the layers and I couldn't scrap with the template. But since I've started to exclusively use PS, I've been saving the .tiff files just because it reduces the size on my harddrive and I can see the file image without having to click on it.

But really its a personal preference thing. Do what is right for you now and as you grow, you adjust and change then.
