How far back in my backswing should I be going?

Of course. I've used different words to start, but like 90-95% of the time it's been this one. And I'm unlikely to switch now.

Welcome to TST @Camjr.   We're glad you've joined.  

Angle is not a factor. I hit the ball 100’ high. Par is net birdie. My CH is 16. The rough between the bunkers is like 10’ wide though. That’s not something you’re going to try to hit on purpose. Most of the area to the left of that is fescue/native vegetation and I’m pretty sure there isn’t a flat lie in any of it. It’s the second hole.

Hello all.  I'm about to be 57 yrs old, started playing when I was 16, and have quit and restarted the game more times than I can count.  I had started playing a weekly round with a friend, and finally made the jump to Senior A shafted Tour Edge clubs.  Instantly gained 10 yds with an easier swing (why didn't I make that jump sooner???).  Glad to be a part of the group. Cheers all,

I think I like this hole.  It is a clear "Risk-Reward" choice.  Since most of the shots in your cone cleared the bunkers I would say they are a minor risk and not a big issue.  Playing the aggressive line may give you 70ish yards in from what looks to be playable rough while conservative play is 120ish from fairway.  I know you said 70 vs 120 is minor for you but how does the approach angle in impact your results?  I figure both strategies are playing for Birdie since holing out from either is mostly luck. Looking at your proximity hole I think it says @ 50 feet when hitting from the fairway from 100-150 and 40 feet if hitting 50-100 from the rough.  Neither of those is an easy birdie putt.   I like the approach angle from the rough between the bunkers & the adjacent tees over the angle from @ 120 in the fairway but I really do not like the idea of hitting onto the adjacent tee boxes and that may impact my confidence with making the shot.  Also, too far left may be a worse approach angle then from the fairway short of the bunkers. For me this may come down to how confident do I feel when I reach that tee box.  If I am stroking it well off the tee leading up to the hole I would try for over the bunkers and the better angle in but if I am struggling that day I would likely opt for the fairway to take more bad stuff out of play.
