I have a 75B, and also the 75D PCR. I enjoy shooting them both, and carry the PCR almost daily.
A friend of mine has the steel framed SP-01 and that is what I would recommend. While I am not a big fan of light rails, I can handle them on home defense, and range guns. The SP-01 balances really well, and the upswept, newer style beavertail allows a little higher grip. I really like the feel of the gun, and the accuracy is superb as with all CZ's.
