A35 and A30 are the names that Pro One originally used for the Blue and Green rears, respectively. So a BSR Blue is the same as an A35, Green is the A30. Not sure whether Jaco Green/Blues are the same (but I would feel pretty safe saying that they are.)

The A35/Blue is an excellent rear tire for mod, but I like the A30 for 13.5 because it has similar forward-bite to the A35 but has less side bite, so the car rotates a bit better.
