How much will adding a ~7g tip weight affect club forgiveness, particularly for a long iron?  Specifically, I am considering order a TS1-IM 4-iron but am tall (and therefore most irons are overlength) and do not want it to get too long. As a result, I’d like a headweight of around 256g, which would require handpicking a heavy head and then adding another 7g or so.  I could use lead tape, but the TS1-IM aesthetics are so good that I’d hate to add lead tape if a tip weight could achieve the same without altering forgiveness (CDIM and VCOG really) substantially.  Thanks.
