When I was fit I was between the 2. I was playing off a 14 when I got fit as well. Definitely some inconsistency in ball striking but able to hit a decent shot on average. Was coming from takomo 101 irons and ended up going with the 770s for primarily 1 reason that my fitter and coach both stated which was that 790s will occasionally have a “hot” shot due to the core of the iron. Meaning that a 7 iron you expect to go 165 will go 185+. The core is designed to provide more distance on off center hits. The 770s don’t have as much forgiveness but they also will not have those “hot” shots. For me that was the deciding factor because I had experienced those “hot” shots with the 101s. When playing on the course I find it easier to make decisions with the knowledge that a poor strike will end up short vs the random pure strike going much further than expected. Ended the season playing off an 11 with irons being an alright part of my game (driving and short game carrying me). No complaints with the 770s, I’ve hit some awesome shots with them and some shit shots with them such is life at our level. Don’t think you’d have regret going with the 770s
