Hey bab
I’ve not yet had my op or anything but I’d say 275 and 300 are not much difference and everyone says go for the bigger option but personally go with your gut.
I was offered 325, 350 and 375 and I’m doing 350 as I know 375 is not what I wanted. Whatever is shouting out to you more go for
It and there isn’t much difference between a 25CC
I’m more freaking out on the profile whether HP or MP bit id
Personally say 300
Good luck bab xxxxx
