ISP will know that you use Tor if you don't put a VPN in between. VPN's a much more commonly used so it raises less suspicion. Not saying that 50% are compromised. Just saying that > 50% are in just two jurisdictions that make information exchange likely. Recently DNM have been taken out by German police. More hops would be nice, especially since overall Tor speed grew by a big factor in the last 3 years. Need to look into how onion nodes view the network. Which makes me think that i2p is even more necessary than I thought first.
