Josef,
My standard hunting bow will shoot a 600 grain arrow around 170-180 fps. My choice is not to shoot anything much slower.
I have bows that will shoot a light weight hunting arrow (480-525) in the 195 fps range. These are all recurve bows.
Arrow speed is a function of bow weight and efficiency of bow design (how efficiently the bow transfers energy to the arrow). Most traditional bows transfer energy more efficiently to a heavier arrow than to a lighter arrow (this is why most bows are quieter with heavier arrows).
My opinion is that a bow that shoots a hunting weight arrow fast, is always better than one that shoots slower..FOR ME. I think a faster arrow shot at game allows for less reaction time and truer shots.
Some folks are focused on speed, some are anti-speed. It is the shot placement that counts. It is just better for me to use as fast a set-up as I can shoot accuratly to make sure my target is in the same place when the arrow hits as it was when I released.
But... like a lot of things "to each his own". Whatever works, works.
