How did you attach the bag?I have had the RKA tankbag for almost a year and am very pleased with it. Its big enough yet not too big. It uses a three point attachment strap system that doesn't scratch. It also has a hidden side compartment for running wires. For example, I can connect a cable that otherwise powers my heated gear to one end by the seat and the other end has a USB to recharge my cellphone, or GoPro up on the handlebars.
The only downside is the map pocket is a little smaller than I'd prefer but I can deal with it. RKA offers a larger map pocket but it hangs over the edges of the tankbag and I don't care for the looks.
It also keeps its shape which is better than some of the less expensive bags as they end to flatten out.
There's lots of choices. Good luck in your decision-making.
