I think blasties have great thaw rate, at least the scientist told me its 70%...maybe do 1 FET and see how that works and you are still in time to do a stim cycle before the end of the year to rip of the 'safety net' benefit...as far as I know, you can do a stim cycle straight after a FET one...

But do find out those questions you have in mind before you start your FET, ie. immunology testing etc...because you don't want to waste a perfect blastie if something there need to be fixed first...
