Thanks to all that replied to my original post with advice/thoughts/perspective re: the 1000/1300 call spread. I know it's been commented on subsequent to here, too.
Again, as with golf, I'm a long-time beginner when it comes to options. Sometimes I hit the fairway, but more often than not, I shank the ball deep into the woods.
Having said that, as others have said, I learned that if you buy the spread, you basically should plan to hold to duration if you want to maximize the gain. I learned that the "hard way" on another spread I did last year, where my thesis was right, but it ran too fast for my long-dated call spread and I didn't realize full appreciation because BOTH legs went up in value. Though, a wise person once advised that if you can get a quick 50% of your max profit pretty early, it may be worth selling at that time, rather than waiting it out an extra year or whatever to get the other 50%. Or "roll" I suppose, if functionally I knew what that really meant (unless simply selling your current spread and buying a new one for the same price).
But to complete the exercise, I did wind up going out to June and buying the 1000/1300 call spread. Paid ~$47. Probably longer than I need. But my thesis/experiment was "Can I 6x my money in ~2 years with a measure of comfortable risk". Not trying to maximize it, but pick a trade I had high confidence in, and then hold to duration. And not sweat about for 2 years (assuming price appreciation is same or better than expected). So for a lot of reasons, I may be too bearish/conservative, and June 23 may be less preferable than March 23. But for this particular trade, I thought the extra quarter would give me a little extra comfort and I wouldn't sweat if I didn't make the perfect trade. But I will maybe play with some others, including a more Out of the Money straight Leap.
Thanks for all the wise advice about rolling to expand the spread and squeeze a little extra out of the trade if it starts working in my favor.
