The 2017 Compstick comes in 17, 20 and 23-inch bar options. The 17-inch bar comes stock with 20 meter lines and is recommended only for small kites (usually 4-7meters). The 23-inch bar comes stock with 27 meter lines and is recommended for larger kites (usually 13-17meters). New for 2017, the universal 20-inch bar, which can be used with any kite slingshot produce, will now come with 20-meter lines installed and 3-meter extensions in the box. This gives riders the ability to choose between two different line lengths. For easier launching, faster turning and more responsive handling, the 20-meter lines are ideal, while the extensions will provide added power, low-end range and higher jumping.
