“everyone holds grafted is pasul. ”
This isnt completely true. Although certainly most hold that way. and even if it is passul, according to many (Taz for example) it would be a pesul of chaser and only be a problem the first day (and perhaps second in chutz laaretz)
Polsih Chassdim (such as Ger) are not too worried about murkav as there is a Teshuva from the sochatchover (the Avnei Nezer ) allwoing it (I dont recall if he allows it lechatchila or only bedieved/beshas hadchak)
