I almost always ask for a discretionary descent and ATC usually works with me - no problem. One of the worst was going from OK to VA; ATC just hada hard time working us in with other corossing traffic I assume and always tried to work us down way too far out for our liking - but it all works out in the end

Yeah - I imagine they might get a llittle nervous - but I've always made those restrictions (so far and knocking on wood!)
