i'faith, it's not about arrow speed numbers, it's about a bow that just fits and feels right.
though there are some exceptions, for the most part aggressive r/d longbows will be faster than mild r/d longbows and those will be faster than reflex or straight longbows. 'faster' can mean somewhere between a few fps and the difference between a ferrari and a vw - in all circumstances there is no substitute for testing before purchasing.
a few years ago i gave away the last of my chronographs and it felt every bit as good as when i ditched the compound and sights 30 years ago and returned to stickbows.
my advice is not to get caught up in the speed game. yes, it's not easy to try before you buy, but it truly is the only way to zero in on a bow that you agree with and vice versa ... one of the main reasons so many good bows can be had used and why the classifieds traffic is so high.
as always, ymmv - but it shouldn't by much.
