FYI, the Red Top is classified as a "Starting Battery", which means it has more Cold Cranking Amps, and it is not designed to be constantly drained and recharged like a deep cycle.
The Yellow Top is a "Deep Cycle", with less CCA's, but can discharge and recharge with little to no ill affects.
The Blue Top is a hybrid of sorts, more CCA's than the Yellow, less than the Red, but is also a Deep Cycle battery like the Yellow. Kind of the best of both worlds. They are also the most expensive if I remember correctly.
Yellow Tops are also the hybrid you speak of.
The cheap Blue Top, 34M, has the same specs as the 34/34R Red Top, and is just a starting (not deep cycle). The other 2 Blue Tops (D34M and D31M) are deep cycle and starting.
Starting batteries:
34/34R Red Top: 800CCA, 1000CA, 110 reserve
34M Blue Top: 800CCA, 1000CA, 110 reserve
Starting and deep cycle:
D34/78 Yellow Top: 750CCA, 870CA, 120 reserve
D31M Blue Top: 900CCA, 1125CA, 155 reserve
Note that I only listed the best of each. The Blue Tops are still the best, though.
The threaded terminals might be handy if you like to remove your trunk setup a lot. Well, if your battery was in the trunk!
