if you can't reach the par 4's in 2 shots, then, i dunno what to tell you, other than youre playing the wrong tees lol. golf is hard man, eagles are tough, and hole in ones are near impossible believe it or not there are pga tour players who get a hole in one in a tour event and it's literally their first hole in one EVER, meanwhile some low handicappers have multiple hole in ones in their lifetime. I have 0, but I'll take near par rounds over a hole in one while shooting 80 any day. I only just this year got my first eagle after driving a 260 yard par 4 and draining a 15 foot putt. I've started to come close on some par 5's this year too as I'm now starting to hit the green on 2nd shots, but again, my focus is not on getting the eagle but rather setting up easy birdies and making pars as my 2019 goal was to break 80, which I now do regularly, so my next goal is to shoot par on a full 70/72 course.
as far as advice goes, you probably just have to be better. eagles start with a good drive and a solid 2nd shot. Know your distances, and be a solid ball striker so your shots actually go those distances 80% of the time, not just once in a blue moon. I mean, unless youre getting 3-4 birds a round, what makes you think you deserve to get eagles?
Interesting. Sometimes at the range I'll play a "simulated" round. I pick a local course I know well and imagine I'm there. First hole, 399yd par 4, hit Driver from the tee. I pick a particular target that represents the fairway. How far I hit it determines the club I pull for my approach, and I pick a different target to aim at so I'm not hitting on the same line every shot. And so on.
On the green do some specific drills, like Michelson's circle drill. Also, use a couple of tees to make yourself a "gate" that is about an inch wider than your putter. Put a ball between the tees and stroke some putts. This will train you to strike the ball in the center of the putter face. Heel and toe strikes will mess with you.
In addition to sharpening your short game, if lag putting is a problem then yes, you'll have to work on it. There's a thread on the "Swing Thoughts" page, I believe, titled "Do NOT accelerate when putting", or something to that effect. I've worked on this since I read it and it has improved my putting, especially my lag putting, a lot!
Sometimes, just work on putts from 3' to 5'. If you make a bad lag, and you will, we all do, those are the ones you have to make to avoid 3 putting. And, if you stick your approach close, those are the ones you want to 1 putt. I've heard more than one pro say that it's important to see the ball go in the hole! Over and over again. Practice success!
I am playing a set of Mizuno MP-18 MMCs, and really like them. They have a thin cavity, thin top line, and minimal offset. The SC version would also work. New MP-20s would be similar.
Also if you don't mind a bit thicker top, something like the Callaway Rogue Pros are smaller headed with very little offset.
Again every company makes a small headed cavity back at this point.
Might also want to check out some of the component options. Maltby has some heads that would fit the bill if you don't care about what name is stamped on your irons.
True that! There was a time when I played a lot of tennis. I, and a friend, would play almost every day after work, and we got pretty good. He was 6'3", I'm 5'9", and he liked to take me deep and charge the net, Once I figured how to hit a deep topspin lob, he stopped doing that!
