Installing choke tubes for a beater gun won't add enough to its value to make up for the cost. And the benefits of choke tubes may not justify the expense, unless you're a red-hot sporting clays competitor who'll do anything for a 1 per cent improvement in your scores.
As a bird hunter, having had several SxSs with tubes over the years, I've found them to be more bother than they're worth...carrying a case of tubes, choke wrench, etc., and cleaning and lubing tubes. And of course, if you're fixated on having the 'right' choke, you have to carry several kinds of ammo so you can have the 'right' load in each barrel.
No knock on choke tubes - they make sense on single-barreled guns where you otherwise have no choice of chokes - but on SxSs, I think they're oversold. Even with tubed guns, I wound up using pretty much the standard chokes and loads for bird hunting, anyway. So in the interest of reducing clutter and simplifying hunting (and life in general), I've gone back to fixed-choke guns.
Chacun á son goût.
