I ordered my Hellcat VI yesterday. My research has turned up the 2 D'Addario sets that are lighter - XL155 and XL156 (24-34-44-56-72-84) and the Fender and LaBellas that are the standard bass VI gauges. 25-95.
The Ernie Balls are 20-90 and I think they have guitar ball ends.
If the Hellcat tuners can handle 95 gauge bass strings, I don't see why they wouldn't handle 100's. The challenge is going to be finding short scale strings in the gauges you want. Standard bass scale strings would require you to wrap 4 extra inches around the tuners - not likely. Or you would have to cut off so much of the ends that you run the risk of the wraps falling apart.
The D'Addario EXL 160S shorts are 50-70-85-105. The ENR71S "half rounds" run 45-65-80-100. You might have to mix and match them with some strings from baritone sets 12-16-22-38-52-68, 13-17-26-36-46-62, etc.
The challenge is that the highest ptiched strings on the Hellcat also have to be the longest because of the layout of the tuners on the headstock. So, standard bass strings are too long and I'm not sure all baritone sets are going to be long enough.
I feel like I've just entered the world of red headed step children.
