FULL DESCRIPTION
Catalyst is the next step in graphite iron design. Featuring our new Iso-6 material technology, Catalyst is engineered to replicate steel alloy properties over 100% better than traditional graphite laminates. This allows for an extremely stable shaft that maximizes constancy and distance control while providing the benefits of a graphite body design. Catalyst also features a reinforced tip section which, unlike traditional graphite, delivers torsional resistance comparable to that of steel—improving stability during turf interaction for better impact on less than perfect shots.
ISO-6 is a revolutionary technology that bridges the gap between what a steel shaft is and what a graphite shaft can be. Traditional graphite laminates are only 35% as symmetrical as steel. Through advanced material modeling and analysis, Project X engineers constructed a new laminate design to eliminate weak spots found in graphite iron shafts due to the lack of symmetry. With ISO-6 being 75% as symmetrical as steel (over 100% better than traditional graphite laminates), graphite iron shafts made with ISO-6 provide superior accuracy in comparison to the competitors’ shafts.
FULL DESCRIPTION
Multi-Step Lite is designed with a unique step pattern that creates tip flexibility for players seeking higher launch angles from a steel shaft. The extended parallel tip section of this irons shaft allows multiple trimming options for nearly all golfers.

Questions & Answers
Ask a Question-
Can these be use in hybrid or fairway clubs?
They can be used in any clubhead that requires a 0.370" tip shaft. Most hybrid clubheads take 0.370" tip, and most fairway wood heads take 0.335" tip. But please refer to the manufacturer sites for exact hosel/tip size information. Or you can send us a message here (help@grips4less.com), and we can also help determine this as well.

Shaft flex used to be designated as "lite, senior, regular stiff, etc. How does the new designation of 4.0 , 5.0 , 5.5 compare to the old system.
Here's the mapping of "Project X flexes" to traditional flex names:
4.0 = Lite flex (like senior or ladies)5.0 = R flex5.5 = R+ flex6.0 = S flex6.5 = X flex
