The Stealth S19 stick is overall a great stick. The stick is longer that most sticks, but comes that way so that you can cut them to match your height. I'm 5'10" and ordered a 100 flex stick. If I kept the stick at the length it came in, it would have a 90 flex. However, because I did cut it (there are lines on the stick where to cut), it is 100 flex at my height. If cut shorter, it would be a 110 flex.
The stick is very light and if you have purchased and played with Synergy sticks in the past, you will not be disappointed. I've owned my fair share of Synergy sticks, and even though the S19 is the most expensive stick I've ever purchased, it is well worth it.
