There isn't an organization that will allow speed pros to be shot that I am aware of.They are below the 5gr rule for IBO and will put you above the 280 rule for ASA.
So they are pretty much useless for 3-d.
The Pros winning in the ASA and IBO are not using "speed" bows.They are using long a-a bows with forgiving riser designs and decent brace heights.
Although,Tom Crowe a senior pro did just pull out a win with a Monster.
