Something else that's pulling me towards the Explorer card's lower annual fee. You can now get up to
60K bonus miles (
http://www.TheExplorerCard.com/60Bonus). 50K after first purchase and another 10K if you spend $25K in the first year. That 50K is the most enticing part. Plus the first year is still free. No sort or signup bonus on this card and no PQMs?
