There are many more things you could do (beyond the three things you mentioned) when faced with the happy problem of having long calls moving in your favor. Another possibility is selling half as many itm calls, e.g. at the 26 strike to create a backspread with less-than-zero risk. You bought the 27.50 for a .10, you can sell half as many 26c for about 2.00, creating a call backspread for a 1.80 credit where the max risk is 1.50. Yummy.
