So you can do what you did and add head weight to counter the grip weight. You can find lighter midsize grips, which obviously isn't always a viable option. You can also find shafts with more tip heavy balance points. You could also add a little length to the club to get that weight back. All these options have pros and cons.
My personal feeling on SW is that it's mainly about getting a consistent feel through your irons and wedges. I don't care about matching woods, hybrids, putters to an iron SW. Most important for me is a smooth weight progression through the set so each club is getting heavier moving from driver to wedges.
The simplest option is start out with just the new grips and no additional weight at the tip. Use whatever iron you want, and hit some balls with impact stickers, foot spray powder, dry erase marker on balls, launch monitor, etc, to look at your impact pattern. Then start adding some lead tape to the back and repeat the process. At some point you should find your consistency is at it's best and adding or taking away weight from that point is detrimental. Then just add the same amount to the rest (remembering head weight influences longer clubs more than shorter so you may want to shave a gram or two off in the longer irons vs. the shorts).
Only other thing to look out for if you add weight to the clubs is how you hit them at the end of the round when you are tired compared to the start of the round. Most people can handle an 130g shaft for the first 5-10 swings, but not necessarily by the end of the round.
