I'm thinking about switching from YTTV (which I like) to Sling to save a bit per month. Right now I'm thinking about getting the Sling orange package and adding the sports extra add-on.
I haven't looked into it too much in depth, but I think the total would be about $40 (before tax)). My bill the last month with YTTV is around $71, so this would save a bit.
Of course there are tradeoffs. Looks like with the Sling Orange package, you can only stream on one screen/device at a time. Not terrible for me, but I would like to be able to stream on up to 2-3 (if not more) devices/screens concurrently. Also, I feel like the apps for YTTV are pretty solid (on Android, my iPad, a Roku, and a fire tv stick), so hopefully the Sling apps are just as solid
