RE: how many pins to use
i use three pins. my bow is also about 260ish. i use a g5 ME sight that has three stationary pins and one moveable pin. my pins are set up for 15,25 35. the last pin i move to what i want, usually 40. but i shoot competive so that distance changes. but three or a good single pin is all that people need these days with how fast bows are today
