Not sure you lose that much accuracy. I had a Bowtech BKII when they came out. Brace was 5.5 if I remember correctly. I've been shooting a long time but I'm not a pro and doubt I have real good form. Self taught.

I had no troubles with accuracy. I didn't wound any critters. Killed several deer, turkeys and antelope with the bow. Hunt and live in SD so many of the deer were taken wearing heavy clothes and no troubles there with brace either.

You may want to shoot some of the newer speed bows before knocking them. All those stories you hear and repeat about shootability may just not be true anymore. Where are you conclusions that they are not accurate and people are wounding a lot more animals with them drawn from?
