Ok, I have a PSE typhoon bow I just bought and it has a drop away rest with nothing else touching the string. How fast do you estimate it can throw a 350 grain arrow? It is rated at 298 to 303 from PSE, so throw in the factor of the lies they tell, I am guessing it is actually more like 270 with a 350 grain arrow at a 70 pound draw. I dont have a chrono to test it on so I am just guessing. Let me know if you have a more educated guess. It is currently set a 60 pound draw but will be turned up close to 70 during the elk season. EJ
