I have ~99% of my trading account in ITM LEAPS. IMHO, ITM LEAPS offer a great tradeoff between risk and potential reward (i.e., I sleep well at night rationalizing a low theta burn, comparably low premium for IV, expiry relatively distant in the future all combine into a rather low risk of losing all my money -- plus if something goes wrong, I can still roll out). Generally, I'm trying to lever up when the stock price is low, and lever down when the stock price is "high" (unfortunately I don't have a systematic way so going by my gut). This LEAP-centric strategy has allowed me to go ~23x since Feb.
My core LEAP position (which is not LEAP anymore however) right now is Sep '21 400 CALLs. This is already pretty aggressive for my taste with "pretty close" at the money and a "pretty soon" expiration; my plan is lever down before or after FY20 earnings, depending on whether I'll believe we have a buy the rumor type of development before the release or not.
Generally, I try to accomplish 1.5x to maximum 2x delta compared to common stock. I found that this offers the best risk/reward ratio for my personal taste (plus I have to pay taxes on these trades so I need to achieve at least 1.3x vs. common stock for this to make sense -- in Switzerland you don't pay capital gains tax as long as you don't qualify as professional trader).
Do you have any specific questions?
