What's the biggest tank bag you haved used successfully on the 08/09 Ninja?

I just bought the Rapid-Transit Recon bag yesterday. It takes up alot of room but it seems ok so far :)

Does it obstruct your view at all? Restrict movement? Mount securely?

That's what I was looking for. A bag with enough space for a weekend.

Is this it?

This is the bag here (http://www.rapid-transit.com/rt/products.cfm?products_id=1219).

I have only had it a couple of days. I put it on the bike after I bought it and drove home with it. It didn't obstruct my view of the gauges at all. I don't know if you could get enough stuff in there for a weekend though. It is a little narrower then it looks. I bought it so that I can keep my work out stuff in it. Once I get my shoes, shorts and a t-shirt in it, it is pretty full.

One more thing about it that I liked is that it is two bags in one. The tope half (more like 2/3) of the bag unzips from the bottom leaving a much smaller bag if you need it.

Forgot to add that the magnets on it seem pretty strong. I don't think it is going to go anywhere.
