I shoot a very ordinary bow,a Hoyt Dorado with Tradtech carbon limbs.
With my 610g hunting arrows it's a tack driving,smooth drawing,very easy to shoot bow chronoed at 180-185fps.
With the 350g Redlines I shoot competitions with,it's still smooth drawing,not as forgiving,but very accurate and ultra flat shooting with good form,some where around 210-220fps.
As much as I love the speed thing,,speed is not everything and I know I can make a good medium speed bow become pretty darn hard to shoot well by pushing it to much.
