High brace, more #.Low brace more speed?

[nyamazan]

I've read that raising brace height increases poundage and lowering brace height increases arrow speed.
Is this correct?
Would these adjustments not balance each other out?I mean more poundage should increase your arrow speed, and the longer power stroke should also increase arrow speed.

I'm not after more speed just curious as to how it all works out.

The longer stroke trumps the slight increase in poundage at higher brace height. Adding an inch of draw length is roughly equivalent in performance to adding 10# of draw weight, I've been told.

For each inch increase in power stroke (brace height or draw lenght) while maintaining the same draw and arrow weight you add 3 to 5 fps.

For each pound of increase in draw weight while maintaining the same arrow weight and draw lenght you add 2 to 3 fps.

These are approximate numbers, but power stroke does have a little advantage over draw weight.

I've only heard that a lower brace height will give you speed and a higher brace will make the bow quieter. Never heard that a higher brace will increase draw weight. I just cranked up the brace on one of my bows and it did not register any higher draw weight at all. Which seems to stand to reason as you are not really changing anything except shortening the actual distance you physically pull on the string to get to full draw. Maybe I'm missing something but I don't think you get more draw weight.

You're right Deads.  Increasing the brace height doesn't add draw weight.

I actually read it on a tuning guide (easton I think), that if your arrows are showing strong to up your brace height. that would equate too a stronger poundage.
As I say I'm new, so I'm by no means stating what actually happens, just surmising and confused. I'm told this is not unusual!!!

I was thinking about this the other day and have read each theory. I thought of it in an extreme case of shorting the string say 5" in length then you pull the string back to your full draw that must flex the limbs back more because the string would be so short between the limb tips it would really put them under a lot more load or strain and it would stack really fast if not snap your limbs. So i think on some bows it may increase # at full draw. Not much but maybe 1-3 pound per inch of braceheight, and most bows only have a window of 1 inch of adjustment.

The new dvd that comes with Black Widows says something about the brace height and a stiff arrow. It has more to do with the string releasing the arrow sooner than poundage.

I think the extra cast you get from a lower braceheight would make more diff than what little you would gain in poundage which is why most tune from higher braceheight down to the sweet spot. But i also think every bow would react differently depending on design of limbs.
