I have heard many different opinions/answers. But, generally speaking, a longer brace height=more accuracy, less speed. Shorter brace heigth=less accuracy, more speed.

In general terms yes.

Very general yes. Brace height is beginning to be not as important. I bought a new bow last year and one of my criteria was no shorter than 6 inch brace height. I ended up with a hoyt katera with a 5 inch brace height. I shot this bow better than any bow i have ever owned. I was always a good shooter but the hoyt katera made me a great shooter. One of the other things that gets overlooked is length of the riser itself. A shorter riser with a longer brace height is going to be equal to a bow with a longer riser and shorter brace height. That comment was from hoyt themselves when talking about the 5 inch brace height on the hoyt katera. With the new parallel limbs you are going to get a little bit more fogiveness with a longer riser and shorter brace height than what you use to see with the non parallel limbs. The brace height and riser length all have to do with arrow travel and arrow contact time wiht the string.

Mike think of it this way, your arrow is on the string the entire shot and does not leave the string until the string is returning to its neutral position. Sooo if you have a 30" draw with a 6" bh the arrow will stay on the string for 24" after the release, giving the shooter more time for error. The fall away rest and the higher speeds have helped on this, but not all. If you are shooting better...good. I coach a lot of people, and I myself was coached years ago. Always listen when someone offers help, you don't have to take their advice but listen. I would say more than half will not listen when I try to help, I still think that they will go somewhere else and try! This advice and a dollar will get you something at the dollar store.

Pretty much and above has stated why.

Brace height in relation to speed pertains specifically to power stroke. Essentially the greater the power stroke the more energy transferred into the arrow.

A 29" draw with an 8" brace has a 21" power stroke
A 29" draw with a 6" Brace has 23" of power stroke

More energy is transferred to the latter resulting in a faster arrow speed (all else being equal)

But that generally gives the archer more time to torque, peek, drop an arm etc resulting in what we call a generally "less forgiving" bow.

The longer brace gets the arrow off the string faster giving an archer less time to screw up.

Torque issues are probably the most common detriment with shorter brace issues.

Now back in the day....risers were 2/3s the length they are now and the limbs were a lot longer and with much less an angle from the riser than most of today's bows.

The longer a particular bow is the less susceptible to torque it is generally.
Spin a 6" pencil in your hand....now try it with a 24" pencil. Which takes more energy to spin?;)

Than we started to see "parallel limb" bows.
They shorten the ATA making bows "smaller" while stretching the riser to compensate for the lack of limbs (making it harder to torque) and use much shorter limbs. The added benefit was a great reduction in "jump" at the shot as the limbs cancel each other out when you get closer to parallel.

Knowing this we can make an educated guess on how a bow will perform just by looking at pictures and specs.

From a picture I'd be more apt to shoot a short brace Hoyt than a short brace Mathews or Bowtech.

Why?

Look the limb pockets and limbs.
Knowing the shorter brace are notorious for amplifying torque issues...the "Thin" width bows, while light and fast, are much easier to torque than the Hoyt with it's bigger (and heavier) limb cup pockets and increased width due to being a 3/4 split limb.


Wow...I don't know what happened there:yikes: I started to post and say "yes" and just never quit typing:lol:

Anyway...YES:D

Besides everything thats been outlined so far.....overall fit has a lot to do with how accurate a person shoots.

Case in point... I have a 2007 Hoyt ProElite target bow for spots (long ata, long brace)

This past fall I picked up a new hunting bow...a Hoyt 737....shorter ata shorter brace height.

I found the 737 holds steady for me better than the ProElite.

Sooooo, I have all my target stuff on my hunting bow and my black and chrome beauty is going up for sale.....

Makes sense, but I can't find a 24" pencil, lol;)

Seriously, great explanation!

Just a side note...don't think just because a bow has a long brace height that it's going to be slow. Elite has two bows out with very generous brace heights compared to their speeds...

My HCA Speed Force i just bought has a 7 1/4 inch brace height and ibo between 342 and 352. Its a pleasure to shoot it.
