Newbie to play flat leather, square brace head, with a large bow door is good or small bow door is good, please advice!

It is recommended that you choose a bow with a bowgate of 5.5 or more, after the bowgate is small, the configuration of the increase and the life of the tendon as well as the stability of the ballistic trajectory have some impact, the large bowgate can reduce the tendon over the bowgate when the bowgate impact on the tendon. Whether it's a round head or a square head, it's not a bad idea. One problem with the square head is that it is not as easy to tie the head of the string as the round head, so when choosing one, you can consider not to tie it. If you want to use the line to tie, consider the round head!
