I don't see anything wrong with TSF, since it is better than 1.23, it's just sad that 1.23 can't play TSF levels. So make it 1.23(which you probably will already) because TSF can handle 1.23 levels.

Also, I like the style of the pack so far, since the tilesets are all different which adds to the fun of the pack. I hope to see TR2 out this year and I will definately download it.
