I have a Stickshot which is just purely a stick. I tried it a couple of times with different band sets and never really liked it. Until, i put one piece of Thera tube black (32cm long) and the string is 13 cm long. I use 16 mm steel balls and shoot in butterfly, it has about a 7kg (15 pounds) draw weight. I also tried 20 mm steel balls with this and it shoots alright. The thing that surprised me was the power that I got with the 16 mm steel, i urge you to try this setup, and i hope you like it.
