Robert,
I haven't fished Southern Oman inshore so I haven't encountered the big bream that everyone talks about but I took a heap of lead head jigs (dropshots) and soft plastic tails in various colours and weights to Hallaniyat and had a ball. I also use these in Musandam almost exclusively. I've caught everything from GTs to grouper on them. I don't see why they wouldn't work on bream though since they work in other parts of the world on them.
They also don't take up a whole heap of luggage room as you can stuff the packets of tails into those recesses between the big items.
I grew up in the shadow of Tom Ugly's trying to chase bream, mostly unsuccessfully. If I'd have caught one like these I'd have made the front page of the Leader at least!
Oh, and don't fish lighter than 30lb.
Regards,
Trevor
