There is an approach to 29, it is an RNAV/VNAV aaproach that places you
on a nice stabilized final to 29, it can be accessed from the database on the 757 in question.
Atc, though does not like us using this as it place us too far out on the base leg for their taste, however cutting inside the course is quite feasible ( you have to be visual anyway)
29 is not 'rarely used', it is used quite commonly, especially with strong winds out of the northwest.
