Language change is annoying as an old fart but you are wasting your time yelling at clouds. Even you'll probably end up accepting it eventually. At least it isn't another portmanteau.
I can only speak for myself but, I only mined with Ocean because they offered a selection of block templates to choose from. Now they took that away and forced everyone onto the knots template. So I took my hashrate elsewhere.
The % hashrate ocean controls is probably a decent estimate for how much bip110 will get.
That looks like a decent first set. I just recommend covert because I've personally used their beginner set and still use the "free" case in my go kit.
You are right that for some locks 025 just isn't going to work.
My monkeys paws are my favorite picks right now. I have the full set in 025, 020, and 015.
