I also don’t think that will work. My understanding is with even two Wally’s on a hybrid lnb you still have to run a channel stack splitter on port 1 and you can’t run a Wally on port 2.Still doesn't seem like it should work, but maybe there is a strange compatibility with them I didn't know about. Wally shouldn't be picky about the port, so that seems strange to me, but if you have issues with the switch ever, which I think you might, try to hook the Wally to port one on the LNBF and the Hopper with Sling to port two, the Hopper with Sling is intended to work on either hybrid port, due to multi-hopper installations.
