You don't need the speed.I shoot compound at around 300 and longbows at 150+. both kill.
In a compound I would suggest a bow rated at 295 or more.This will shoot hunting arrows at 260 + depending on the weight of the arrow.
The new bows are quieter than the old ones ever were, and they are more acurate too.Don't shy away from a bow because it is fast.If you get a slow bow next year you will want more speed.That's why I recommend a bow that is rated to 295+FPS.My wife shoots a 318gr arrow at 250fps and took a nice doe last year at 40 Yds.Broke it's back and ribs.
Find a smooth draw and an adjustable cam.This way you can set it up without needing modules or a new cam to get the draw length right.
I have a couple reviews on good bows on my site.They might help.
