My draw is 26.5. My arrows are 24.5 ctc. As long as the broadhead clears the riser and it's not so short you pull it through the rest. You can have your arrow as long or short as you want.
My draw length is 27.5 and I did shoot 29.5 " arrows. I wanted a little more weight and stronger arrow. I had to get a stiffer spine and had to go longer. Draw weight was around 55#. Easton bloodline 330. Bare shaft tuned wonderfully and shot excellent. Paper tuning is a waste of time for me. After bare shaft tune and walk back tune my broadhead fly right with field points.
