Why would you not get choke tubes?
I don't need them. The only two barrel gun I own that has them is a Classic Doubles 101. In 18 years since I bought the gun nothing but the I/C and mod tubes have ever been in it. Also, on the CZ guns with choke tubes there is a noticeable flaring of the barrels at the end. I don't like the blunderbuss look, especially if I would never be switching chokes. The exceptions for CZ are the 16 gauge and four-ten which come with fixed chokes. Just my opinion, your mileage may vary.
