The Sls i have thrown and owned have all had more LSS than all the Beasts i've thrown. I have only thrown FLX Avenger SSs which at my power are rollers out of the box. To me the SLs have been impossible to turn without wind and they are more HSS than the Beasts or the probably FR Surge SSs. Meaning none of those turn at full power for me in calm weather but the SL needs more front quarter wind to turn than the others. I agree that the Beast of no configuration is really overstable. That is why i thought that the original poster needs a straight disc like the Beast instead of an overstable one like the thread title suggests. I have only thrown the FLX Avenger SS and it turns like a broken in DX Valk=a lot and Blake's fade characterisation is accurate enough for me regarding the SL but i'd need to add that the fade of the Beasts manufactured within the two previous years is less than that of premium plastics Valks. And on par with broken in DX Valks meaning the amount does not change much and both have little fade. With the Valk having less when broken in and more/the same when new depending on your speed/spin ratio.
To be perfectly clear i state that the Beasts made in the last tow years on average are more HSS by a lot vs an Avenger FLX but having less LSS. Thus i'm interested in seeing how Avenger SSs of other plastics behave vs modern Beasts. When Blake wrote that Valks have more consistent fade than the Beasts i'm not sure of what he meant. Across plastics that would be accurate of older Beasts than two years or newer. The newer ones fade the same each time for me. And Beasts are a moving target because there was the original and different shape and the new mold and the more overstable mold since about two years back that does not flip for a 400'+ 20 revs per second thrower. Like the new molds did. Since Avenger SSs fade consistently too much for ultimate distance for me given my spin constraints i'd say they are very consistent for the LSS even factoring in the less than desirable HSS for the FLX. Other plastics may vary a lot i don't know. So i can't say that the fade of the Beast of any kind is more consistent than the Avenger SS of any kind. More consistent is not the same as the absolute amount fade anyway.
