It sounds like your orfice is a prime suspect, I would check subcooling right before the orfice. does the system equalize when shut down? if yes then it should be flashing at the point of restriction leaving ample evidence as to where the restriction lies. if the strainer was the issue you would see it in your heating performance, did you blow through it in both directions? remember the flow of refrigerant is reversed during heating operation alowing it to bypass the potentially plugged orfice. with subcooling checks you should be able to find the restriction. check the orfice located in the condensing unit itself, look for the restriction while unit is equalizing "flashing"

well even though the system dont have a orfice it doesnt equalize out when system is idle. thanks for the input any way.
