I was using R 11's for months,Starting out they were all right irons .Then made tour master and wasstuck in a rut,Purchased the G20's .first shot with new irons,was money,St Andrews 2nd hole ,could never really get it close ,man i almost holed it.Posted a 30 Wich is good but i see27,28 coming.So buy the G 20'S Worth every credit P.S Dont use the black Max balls,you will have a hard time using another ball.Everything else is to fast. At least for me it was,Good balls,but cost to much.
