There is also something that I might add, the top of Citic is not the same for all four sides, there isn't the hole at the sides( if you are looking from the front.)
All their drawings are 'symmetrical' that's why mine is tilted at only exactly 20 degrees because I'm not too sure and don't want to risk the accuracy.
Also, the base is almost square, and at an angle, it should be very narrow, so the diagrams (besides Buck's and Damien's) have their bases too low.
I hope the change of base can give me an advantage.
Thank you for your comments.
