Girls, i deliberated about the exact same thing 260 or 300, i chose 260cc cause i thought 300 would be too big. Utter nonsense and now feel i’ve wasted my money, really should have gone bigger, perhap even to 340cc to get my desired look. So please go for the biggest, you won’t regret it! I promise you! It’s such a small amount of cc to concern yourselves over! Good luck xx
