Richard, I haven't fished Oman but from what you have written and what I have heard about the location, it appears you're under gunned if half the fish are reefing you.
On your gear, well, first thing to do is toss the KGS 70MH. That is simply not suitable for chasing GTs where you are. It's a PE5 rod and you will struggle to stop a 10kg GT with that. On your 80P/35, I can't believe but I am actually going to agree with Mick on something
You're asking too much from the rod. Ideally it is a PE6 rod suited to about a maximum casting weight of 150g. With a 220g weight on it, the rod will over-saturate when you're casting hard and the only way to cast a weight of that magnitude is to lob it.
In terms of the ideal rod, it is hard for me to give you a suggestion without having seen you fish. Have you read our guide to GT rods? You can access it on this link and some of the information there might be useful for you.
http://www.gtpopping.com/forum/index.php?topic=1374.0You need to find a compromise between casting distance and the maximum backbone that you can handle on a rod. In locations like Musandam and Shoalwater, there is little subtlety once you hook-up so ideally, you want a rod with the maximum power that you can handle.
I personally would be hesitant to recommend the Long Reef for a location like that. It was made for locations where you want as much distance as you can possibly get but the compromise you pay is that the rod doesn't have the power to slow fish down like a shorter, stronger rod and it is a bit more cumbersome to fight a fish with.
If you like big heavy stickbaits and you want distance as well, I'd suggest that you look for something like a Ripple Fisher Ultimo 82H. It's a heavy PE8/light PE10 rod that is comfortable to fish with, casts really well and has reasonable backbone. Note this rod is not suitable for poppers beyond about 130g. It is a stickbait rod, not a popper rod.
You might also find a Carpenter Monster Hunter MH80H to your liking. This will cast big heavy stick quits easily and also handle decent sized poppers and has a heap pof backbone low down.
If you are struggling for distance at the moment, I'd suggest you avoid the shorter rods like the Tokara.
