Should I buy a wedge?

Here is a link with all of the lofts providing that is the club you are referring to.

     Sand wedges generally come in lofts from 54-58 degrees and what separates them from other 'wedges" is that they tend to have more bounce - 10 degrees and up. Do a search on wedge bounce on TST, there have been some great threads with a ton of information on what bounce is and what it will do for your game.

     Whether you need one or not is up to you. If you are having problems opening up the AW/GW then maybe you would benefit from a higher lofted wedge, but it is also important to understand that if you do not practice your short game, a higher lofted wedge will not help. 

Wedges "usually" come in lofts with 4* of separation. I know the "standard" lofts to be Pitching = 48*, Approach or Gap Wedge = 52*, Sand 56*, Lob 60*.  These lofts can vary. You have a PW and AW. You do need a Sand Wedge for just that, getting out of the sand. Sand Wedges usually have a larger Bounce to help prevent the wedge from digging into the sand. I find the SW usefull for hitting chip shots around the green as well, others may use their Approach wedge, or a Lob wedge. You may want to hold off on a Lob wedge as they are a little tricky to hit and take a lot of practice. Hope this helps.

I play four different wedges all four do not come in any kind of a set. For me i am dead on with all of these with a 20 yard space thats why i play all these wedges i think its more important to be able to get more surgical as you get to the hole, hense why there called scoring clubs. I dont feel its important to have a ton of hybrids and woods i only have one of both so i can have alot of wedges. The goal is to get the ball in the hole we all know that so why not make it easier as you get closer. Just my opinion though im the only one of my buddies that has so many wedges but its part of my game i like to play the most.If i where you id throw out some top of the bag clubs for wedges. Everyone has there own opinion but you will probally hit more wedge shots than shots using a 3 wood from 200+. Hope this helps this is just in my opinion eveyone has one some good stuff posted so far Agree with the 56 and a 60 they are both more user friendly than say a 54-58 but you have to start somwhere i like my 50* for 105 yard shots right on the money. I just posted a forum about me swapping out my wedges. I hightly recommend scratch golf. American made And they can costomize anything you want for a stock price.
