Are you aware that the higher your meter speed rating, the slower the meter returns so that you are more likely to hit the ding? Your clubs and balls do not necessarily have to have the same rating however they should be as close as possible. If your new Lvl 90 irons have a meter rating of '3' I suggest you try the: Callaway ERC Soft SMB (L34+) D 4.0/ S 2.5/ DUR 2.5/ MS 3.5 (Cost 450). Good distance, high durability rating (around 120 or so hits per ball not counting putts) and a slightly slower meter. They will go very well with your current Callaway Mavrik Irons and it may not be necessary to upgrade clubs again until you hit Lvl 100 when the top of the Cally range becomes available to you.
Just by the way 'Flatearth777' - it's round like your balls.
