Honestly, I would say not really. While I originally loved my lizzies in pow, just because they were the first 'fat' skis I had, they aren't really all that good. They float fine for skiing around, but on landings I find them quite tip dive prone. Switch is difficult too. They just aren't really long enough, only 169-170 true length with very low profile/short tips isn't ideal for what it sounds like you'll be doing.
Lizzies are probably my favourite ever ski but I think you will enjoy your sessions a lot more if you get something with rocker, or at least something 10cm longer.
