PSE 200 Extremes w/ 65 gr points would be around 310 gr. Spine may be weak. By the chart they're OK, but in reality may be weak. 300s would weigh around 20-30 gr more. These are both w/ 4" vanes. Doesn't IBO have a speed limit of 280? That may be an issue, if you attend IBO sanctioned shoots. My P38 DC shoots a 365 gr arrow close to 290.
