I dont know of the solar panels you mention, but Canon make some flexible panels and they get a good rap over here.
I have 3 little solid panels that I use. 1x 5 watt and 2x 2 watt panels, and I mostly use them with Sealed Lead Acid batteries.
I have 5x .8 Ahour, 2x 1.2 Ah, 4x 9 Ah, 1x 28 Ah and 1x 43Ah Batteries. I always get 12v chargers for everything I own, or I make one. I have also made some adjustable voltage regulators and keep a range of connections handy for other thing I might come across that I need to use.
I keep a range of thing that work on 12 volt eg compact fluoro's etc
I have all this for everyday use, not as my BOB, but its an easy grab.
