I have a Talon 2 that is sized at a T4. It houses a Sabre 135 Main and an Airforce 120 reserve. I would like to fit a 120 Stiletto to my T4 rig with modifications done to the closing loop, for firmer closing loop pressure. Can this be done safely without having to purchase a new T2 size rig? Any advice on this issue would be of great appreciation. Regards,Richard.
