Not necessarily worthwhile. Remember, if your antenna is optimized for
low-angle weak DX signals, the high-angle signals are going to be much
closer in and therefore much stronger to begin with. If you lose a few
dB on a S-9 signal, it won't matter.

If a incoming signal aligns with the null between lobes then the
receiving station is deaf to your signal. Moving the lobe slightly
upwards can add a few db as you call it and allow for communication. If
you yell at a closed door you do not increase communication, whisper
under the door and you can then be heard, Its all relative. As far as
those that follow lemmings do it all the time.
