Is this set good for a beginner?

Yes. The hybrid, cavity-back irons and high-MOI mallet putter are all built for forgiveness, and the compact club count keeps decisions simple. The wide gaps between irons mean you will need to learn partial swings.

What clubs are in the set?

A 3 fairway wood, a 4 hybrid, a 7 iron, a 9 iron, a sand wedge and a mallet putter. That is six clubs; the seventh piece is the putter counted with the set. No bag is included.

No. The 3 fairway wood is the longest club, built for a higher launch. Off the tee it will fly shorter than a driver, which costs distance but is often straighter for newer players.

What shaft flex does it use?

Regular flex throughout. That suits moderate swing speeds. Players with fast swings may find it whippy, and very slow swingers may get better launch from senior or ladies flex.

Can I add clubs to fill the gaps?

Yes. The obvious gaps are between the 4 hybrid and 7 iron, and between the 7 and 9 irons. Adding a 5 or 6 iron and an 8 iron would close them, and a gap wedge would sit between the 9 iron and sand wedge.
