Which Frame Arm is better?

[Momentum]

Hi,
I just got my new quadcopter and after many successful flights my frame arms broke (twice, and landing wasn't so rough). After some researching, I figured out that you can break it very easily. I already found a site where I can buy frame arms, however they are selling 2 models: http://quadcopters.co.uk/f330-frame-arm-red-360-p.asp[URL='http://quadcopters.co.uk/f330-frame-arm-red-360-p.asp']#mce_temp_url# [/URL]and http://quadcopters.co.uk/f450-f550-frame-arm-red-1pc-276-p.asp
So I was wondering if you could help me decide

Quality on those arms is going to be the same, but the 330 are smaller. What size is your current frame? You probably want to stick with arms that will keep it around the same size since it's built out already to support that frame size. Also, those nylon arms you sent are pretty strong. I've seen frame arms break easily, but the only time I've broken one of those nylon arms was when my TX had a bug and shot my copter straight into my ceiling at half throttle. They aren't the lightest arms you can buy, but they are definitely strong.

I like the DJI Flame Wheel Arms. They are only $4.00 a piece and I have seen them drop out of the sky from 50 feet or higher and not get harmed.
