Distinctive features of English diphthongs

I am looking for a table of distinctive features for English dipthongs along the lines of that available for other vowels here. I don't trust my purely book learned linguistic skills to produce an accurate feature matrix.

A tool I wrote uses a distinctive feature table based on a very old theory and I would like to update it.

I don't know much about diphthongs myself, but the only features I can find are described here. They are:

• closing vs opening (vs centring) (direction of tongue movement)
• wide vs narrow (amount of movement)
• falling vs rising (placement of stress)

Several examples are given, but there is no exhaustive list. Another source (see section 5.5) categorizes most/all of the English diphthongs along the closing vs centring dimension (English diphthongs don't open) and the falling vs rising dimension. Still more categorization can be found here. With these sources, you should be able to build a complete table.
