When you draw a bow the limbs go more than what the shorter brace is at rest. It's not the brace that screws up the bow, it's drawing them past the limb's working range, and a shorter brace will shorten the max draw length.
Not harping a technicality, but a "shorter brace" by itself is not the problem. And it isn't a problem if the shooter doesn't hit the max draw length set by the limb's workling range limit.
The bows become dogs if braced too much, and with most people being stoopid......the bow won't shoot well performance wise and they'll say "this brand XYZ bow sucks!".
When it doesn't.
Same for a too short brace.
And I've seen a ton of folks bring the bows they're shooting way out of tune, crappy arrows/rest systems.........I'm the poor slob that tries to explain WTH they should be doing.
and they go to Waklklyworld and buy vaned arrows, for shooting off the shelf, after saying they want to shoot off the shelf, and agree that feathers are what's needed.
They add double nock points, move them all over and change brace.........and things go from bad to worse, they come into the shop and say "you said this and that" when i didn't.
Two different preachers guys have done this (God must love an idiot).
Guess what..........idiots are everywhere and manufacturers know that many will be buying their products, hence a safe zone of sorts in their "recommendations".
My brace may be high but I get FP's and BH's to hit the same, my bows are quiet and my last two BW's hit 200 FPS with 480 grain arrows, that blew through deer no problem.
Screw whatever the recommended brace is. I'll set it where the bow and arrows tell me it needs to be (forgiveness and low sound level), and so far on my 2 Damon Howatts, 2 Wings, 3 Bears, 1 Locksley, 1 Hoyt, 1 PSE and 3 Blackwidows it's always been at the top end or over whatever was recommended. My buds with Schafers, Bighorns, Great Plains, Elburgs, Chastains, Cascades and Brackenberries all run theirs pretty high too.
One bud running ILF has shot his OK at lower braces, but for hunting twists them up a bit. He shoots 38-42# so is trying to squeeze as much speed as he can out of them.
BTW, my Tradtech Pinnacle 2 is braces a little over recommended max. With different limb types and lengths, drawn to different lengths......I think the recommendations are just a middle of the road deal. Don't think they are some hard set "rule".
I wouldn't go way past the recommendation, seen bows come in with strings a couple of inches too short on them!
1" if the bow keeps its speed should be fine, if it isn't then what the heck will happen when somebody with a logner draw shoots it at the spec?
From what I;ve seen over the last 30 yrs, it's the long draw guys that blow up bows, outside of those who abuse them with heat or poor stringing methods.
For the guys shooting bows over 58" tip to tip, drawing 28"........there shouldn't be a problem with most bows being braces a little over the recommended max.
if they set the range to a real max, then folks would take it there and blow all of them up.
Read: the max is probably set well within a safe limit.
