The Wilson Staff Tw5 wedges are aimed at the better player.
The first thing you notice is that the faces on them are quite shallow and have a long thin look about them, which may not be to everyone's taste.
That said, they definitely do the job and the grooves generate lots of spin and will take a few covers off your ball as a result.
The bounces on the wedges tended to be towards the lower end of the scale and the lie was such that you felt the bounce was even lower.
Therefore if you play off a lot of tight lies then these clubs would suit your game.
These are the wedges Padraig Harrington uses on Tour so if he likes them they must be good.
