hey hey hey! congrats on your progress! i've had my BCE for about 3 years now and i've always paid in full once the statement posts. don't know the correlation between paying in full and increasing possibilities of CLI but i assume since AMEX is king of charge cards, they like to see some of those same habits on revolving accounts. also, if you plan to use it as your go-to daily driver, then yes i think it's a good idea to use it as a debit account and pay every month. you earn points wayyyy faster. good luck!
