I use Rock oil strawberry 2 :) yes, it smells of strawberries!! Not sure if you get it over in the USA, but Ipone also did a strawberry smelling one a while back.
I have used it for years, at 75:1 in my Beta's, 100:1 in GasGas' and 50:1 in my SWM.. it is synthetic.
The reason GasGas pro's run at 100:1 is that unlike most others they don't use the oil in the fuel to lubricate the crank bearings. They run in the gearbox oil so it is more important to use a good oil in there and change it often on the Pro's.
