RE: TP 4200 vs. TP 5300 LiPo Batteries
Never tried the 22x11, but I did fly the 22x12 until recently. With the 22x12 the plane flew very slowly, good for flying at constante speed but as soon as the wind started blowing, I found myself using full throttle for almost the entire flight and still wanting the plane to go faster. Now, with the 21x13 the plane has a bit more speed and it´s easier to fly in windy conditions. If I could go back, I would get a higher rpm power system, like a Hacker 13XL with 20x13.
Bear in mind that I fly at or near sea level, so my experience may not apply to your circumstances.
