Read my set make up i think longer hitter off the tee above 250-280 average for the amateur
should have driver high launch at least 10.5, 4W, 3 hybrid, 4-pw, 52, 56 and 60 degree wedges
but ur question sounds like u have a gap in ur set hit ur 4 iron for average and test some 3 hybrid for the step up get that, then check for a new 3w/4w for the next move up
same for the wedges get ur PW test some 50-52 wedges for the next desired and so one down i have seen good amateur with pw (47) to a 50 52 and 56 cuz of what they are wanting to hit full and how good short game player u r with touch and pedning up the blade and the sole grinds can help out also with a 56 to really be able to open those up
cuz lets face it phil carries a 60-64 sometimes or soemthing like that and we aint phil!!!
but more shots hit one hundred in so get all damn wedges u want to be honest an kick the 4 iron all together5-pw and a 3 hybrid kinda the knew 5 wood and easy to choke down on to hit shorter also with hybrids very high launch with spin and sits easier. have a pw 50 52 56 and 60 that way, i dont hit 4 iron at all on my courses and thinking of doind this so another variable there to ur courses ur playing.
my soap box for the day with the make up of ur bags
