Seeking sign-up &-or spend bonuses since 2011;
peaking 2014 into 2015 with 4-5 new cc's quarterly;
(me+wifey to get best offers x2)
used cc's to pay $50k-100+K/yr IRS taxes & trigger best offers,
easily worthwhile, even with 1.0187% fee; (balances paid when due)


Eager to keep paying taxes with cc's but hit bonus sign-up wall;
no more 2x HiltonH every 70 days, no more AAdv Exec 100K, etc.
are there still any good annual or shorter cc churns???
everything seems to be 24mo churn or once per life now...?

Thanks in advance!! ^ ^ ^
(still novice, need help...)
