Allen, that particular bow has some history to it. I took it to a walk the talk event and it tested out at 188 with a fast flight string. In the official test it tested at 186 because of a very tight arrow nock. After several years the bow had broken down considerably and was actually had a broken glue line at the handle and fade area, current 500 grain speed at the time the record was set was only 172 fps. Not sure with light arrows how fast it shot.
The bow I had high hopes for is heads and shoulders faster than any bow I have ever competed with, it did not do so well. I have some super stiff 188 gran arrows I am going to shoot out of it this year and see if they do better.
