I've got plenty of experience on Omega brakes - and I used to be a brake designer, too......
it's a "swings and roundabouts" thing really. There are pad meterials which are good at working from cold and those which are good at working from hot - there are no pads good at both.
You need to have a think about what you really want as a priority.....
something like yellowstuff will work on the track admirably, but they don't heat up well from cold - a factor which you need to bear in mind on motorways.
a standard pad will work well from cold, but probably won't last a half lap of the 'ring.
I personally don't rate Omega brakes at all - their heat-handling capability is very poor. Even in the 2.6 I can fade the pads every night on the way home from work. And don't even start me on vibrations. I guess it's the price to be paid for a design originating on 14" wheels.
For your venture, I'd recommend yellowstuff, but bear this in mind on motorways.
For my track-day cars that I MUST retain Omega brakes, I use yellowstuff and change them every day ( including discs )
For the track car that I DRIVE, I have a 350mm disc/caliper set that I swap round. Again with yellowstuff.
on a slightly different front, brake pads are all very similar to one another. They all must pass the EU directive to be allowed on sale, so their quality is all the same. There is no such thing as a "bad" make of pads. The only thing that manufacturers are really able to do different in the heat range that they're effective in.
