As others have suggested you can cross at Sandy hole pass. If your your 6ft 4" like me, then you can probably just chuck your sack over and then run and jump over. But with the water flowing quickly, it's an intimidating undertaking and not something you want to get wrong.
It's also easy to cross the East Dart just above the tinner's hut. SX609846 Then, as you are aiming for Princetown, work your way across the peat to Beardown tors. Stay on the high ground, Cut hill, Summer Hill and Devils Tor and it's a pretty simple, flat boring travers. Can be very damp under foot that way. But I have walked it a number of times doing the 600's from Two Bridges.
Hope it goes well which ever route you take.
