Going via the DAL can lead to a loss of manouvering speed due to the turn and the altitude effect when turining onto the final approach. The safest way, although not as efficient is to proceed to the DAM VOR, do a hold entry to position for the outbound leg of the approach. Done this many times without problems, except that if you have a validated FMS approach it may not turn onto the LOC at the correct point in space and the glideslope will be already below you. Use a manually selected intercept heading onto the LOC so to keep below the glide.
