All of the hinge type triggers are good ...it is the quality/setup of the other parts that "swings" it
performance wise.
The Shocktech or Planet Hinge trigger just dumped on any old cocker isn't always gonna be smooth a SFL with swing trigger is smooth down to the other components same applies to the Planet trigger...the WGP one on the other hand is a clusterf**k cos of the height of it in mainly comfort terms. Oh before I forget the Shocktech one, I do like but alot of people will give you **** 'cos of the trigger guard appearance (and it is tournament legal, I was party to the disussion at the last World Cup when a player was trying to get it disallowed...it wasn't !!)
