I've been using a max weight demon lately and loving it. Very similar to a roc but just a tad more stable. Since I have a weaker arm it's a lot easier to control for me and I've been getting some great lines with it.
I just picked up a pair of Demons (one Evo, one sure grip) as well and have been loving them. WAY more overstable than a Roc though...probably the most overstable mid I've thrown in a long, long time. Taking the M1s out for these.
