The Kobalt is available up to 28" draw length at 50-60#, this is what you need. Your archery shop can order it this way. The top ibo speed listed by Hoytis 280fps for a 28" @ 60#.

Sweet bow, picked mine up last night.
Mine is set at 25.5" @ 56#. I have no idea what the speed is nor do I particularly care. It shoots sweet and is whisper quiet.

Good Hunting,
