The weight of the Patriot is 3lbs 12 oz, the matthews lx is 4.25 lbs. The IBO of the Patriot is 320-328 FPS, while the IBO of the LX is 315 if my memory serves me correctly. However, the LX requires a brace height of 6 5/8" to get that speed while the Pat has a more forgiving brace height of 7". Hope this helps.
