It doesn't "need" a
glide because it doesn't move much air. The more airflow, the more bite a wand has.
The 802 and the AW29 are totally different wands, the 802 moves more air than the AW29.
They do make a 14" AW29. Any CMP distributor can order it, it is their model number 1410.
After the Prochem Titanium my favorite wand is still the 14", 5 jet, 2" tubed CMP low profile wand.
If you are looking for a lightweight, maneuverable wand for tight areas that still has good flow and is cheap, look at the Westpak 2 jet low profile wand:

Of all of the 2 jet, 12" 1.5" tubed wands it moves the most air. At least it did when we tested it against the other 12" 2 jetters a few years back. We were really surprised, that little wand sucks like a two-dollar whore.
Take care,
