Another vote for Rinne. Even if you feel Schneider will be better down the road, he's unproven as a full-time starter, and Rinne he's still perceived as an elite goalie regardless of what he could do going forward.
As for the draft, there's no chance Rinne will fall to you. Depending on other teams' keepers, Schneider may or may not be available, but more likely than Rinne.
Another option for down the road if you really want Schneider, you could possibly get Schneider+ for Rinne so it would be unwise to drop Rinne.
All I've got...all I've got is insane!
