Which new track master set works best with the old track master trains?

Those Railway Builder Buckets are very, very handy. Lots of the Small and Large type curves, which I greatly appreciate.
Wish there were more straight pieces, however, but for the value of what's already being obtained when one buys the set... it's a good deal.

I suppose you could try the Tidmouth... Bridge (?) set that just came out recently too. Simple layout, only real raise in track is for the bridge itself, which is relatively low anyway. Not sure how the old Tomy Henry will run on it, with the batteries being in the tender, but... it's worth a shot!

I just got the Percy Sort & Switch Delivery Set for my first Trackmaster Revolution set (I plan on having it in tandem with my TOMY track and having newer engines run on the Revolution line to save filing them) and rather than using the Percy that came with it I decided to see if my TOMY Thomas would do it and he works with it fine so, by extension, the Trackmaster engines should work with it fine as well.
