I use a 707 GM+ from last year. I must say, I've been very happy with it. Even though its a large chunk of wood (2.13 on the scale), its got a very nice balance and with the higher middle gives it a nice pickup. I would definitely go the same route again when looking for a similar size bat.
For me, being based in the U.S., I had to buy one without the benefit of being able to see and feel it in person due to cricket shops being pretty much non-existent in my country, but I would say its probably the tops in my favorite lists.
At the same time, I agree with the others. If you can, check them out and pick up a few yourself.
