Get an angel, you will get quite used to sawing them up and posting them back!
As I has said before as long as you dont use them when it is too hot, or sunny they are ok.
Or too wet, they often break when raining. And they get brittle in the cold, never use them in the cold.
Dont cast into the wind, as this stresses them too much. . And never cast on still days, i have broken mine on a number of times when calm. Make sure it is not too dry, as they dont like this, but fog is a real killer, damp days are not ideal.
Ideally do not use them in winter, and avoid feb until november. I have only broken angels, (and gems, sirrus, and a couple of greys)
other than this i have found them excellent.
