I think the price point is far more important. The Disco and FDPCP do not have that and for good reason. Also the single shot trays seem to be popular with the mrod shooters.
As for loading a .177 pellet in a XS60C with a scope for some it is a challenge. JMO
I bet Xisico could do a repeater PCP for around the Disco price point and it would be a big seller.
