RE: Chek-Mate arrow speed?
The "Firebird XL" <img src=icon_smile_wink.gif border=0 align=middle> or "wannabe" was shooting a 31" Beman 400 with 125gr tip, 30" draw at about 55#, shortish braceheight of around 7", with a dacron string (this was before the Dyna'97 enlightenment) and shot 195-197 fps through 8 arrows.
Haven't chrono'ed it with a Dyna string.
