They usually base your maximum size on your bwd and depending on what profile you choose (moderate, high profile, extra high etc) and what brand you are having they will have different cc’s, the latter profile having the most. Looking purely at your stats I would say you could have bigger unless you have a narrow bwd or have specifically asked for a low or moderate profile. It’s a big decision and if you’re not 100% happy I would def get a second opinion. Good luck!
