Not being familiar with the Ping Anser forged irons, I can only tell you the difference in specs.  The 710 CB's are made of a softer carbon steel, are slightly less offset, are more upright and 1/4" longer.  As far as forgiveness, take your Ping to your local Titleist fitter and hit them side by side.   If you would like the name of a local fitter, give us a call at 1-888-TITLEIST and we can find one in your area.

"Serious clubs for serious golfers"

Based on Titleist's long time committment of producing better clubs for better players, one can never go wrong in using it.  With four different iron models they have you can choose which one will fit you the best.  From the easiest to hit AP1 to the MB's that professionals use (which would be harder to hit), and the in between AP2 and CB.  What matters the most is what kind of results you are looking for... would you go for a forgiving club that will help you getaway with poor shots or a performance club that will satisfy you when you hit good shots.

Again, it always boils down to preference.  With the golf market being friendly now, we can try everything out first before buying!
