What kind of bow is better in recurve bow? Is there any weight adjustment?

If the style of play is fixed, there is almost no difference between the two.

In fact, the function of "adjusting the number of pounds" is only a side effect of "adjusting the upper and lower bow files" in my opinion.

If you always switch between the split finger and the lower three fingers, or like the range of snapping fingers, of course, you should use adjustable, but if you fix it in one of the split finger and the lower three fingers, there is no problem if it is not adjustable.

As for the fluctuation of two Jin, it doesn't make sense.
