Before anyone looses their minds over the UKMO T144 it should be noted that it is still trying to send energy under and up against the block compared to the GFS which by this point has the block receding into Europe. GFS seems to be the most progressive (massive shocker)
I would say UKMO is mid-ground solution at this point in time.
GEM Best case.
ECM is 2nd bite to a longer lasting spell
UKMO is perhaps 2nd bite with a larger risk involved than ECM
GFS has it's sledgehammer equipped and is pounding that block back into Europe.
