If you are in the market to get an angel I would suggest getting a second hand angel speed they can be picked up quite cheap now but you set them up right and they rip. They are also very reliable, low maintainance and you will be able to play with it at any level. The older angels are heavier and not as fast or reliable.
Again if you are at dartford on the 23rd you are welcome to shoot my speed as well as the amg to see the difference then make up your mind.
You can pick up a speed for about £350 - £400 second hand then go see john or chris at london paintball supplies who will do you a 1.1 litre air bottle and angel preset reg for about £170 and supply all your other paintball needs.
one last thing dont believe all the people who talk about kicking my ar$e cos thats all they seem to do.......... talk about it !
