I guess it depend's on the club your shooting at & the class rules & if they inforce them.
At the club's i shoot the rule is in the bowhunter class:a stabilizer no longer than 12 inches & sights with no more than 5 fixed pins.
Also all the clubs i shoot have a web page where you can e-mail the president with question's like your's.
Hope this helped.
