Driver Upgrades?

I’m a fairly average casual golfer, between a 10-12 handicap last year. My home course is a legitimate NCAA championship course, so I’m happy with sitting around a +10 with how much I play. Been slowly upgrading clubs. Bought my first ever set of new irons last year (790s) to upgrade from my R7 set that I had since they came out.

Currently have an R11 driver, recently put a stiff shaft into it, probably later than I should have. Call it 110mph average swing speed, maybe 250-260 average carry. I really like the R11, but there’s no way it can last much longer.

Don’t really care to just go out and buy the latest and greatest $600 driver. I know it’s not going to make that much of a difference in my game.

What would be a good jump up in tech where I would actually see any “benefit”?

I imagine a newer driver I may actually see a 5+ yard jump in average carry, even though the R11 is a fairly long driver as is. I’ve heard about driver face designs as well helping bring down left/right miss deviation which could be a major benefit.

I do like Taylormade, but I haven’t kept up to date on their lines since I got the R11 (it’s been a long time). I feel like there was a lot of hit and miss on some of the series if I recall. Maybe the M1 or M2 was pretty good. Then maybe the Stealths were pretty good? I had the R9 before the R11 and they were both really good to me.
