Hi again John,
You should always have them fitted, wedges more than any other due to the loft.
Depending on your height wedges can be bent in minuets for £5.00 no sure about US. Your other clubs depending on make,model etc can be bent by your pro or like my
Callaway's they have to be done by manufacturer due to the hosel design.
My clubs are:
1 degree flat 3-5
2 degrees flat 6-9
3 degrees flat P-lob
Ian.
