Just go all out. Book a trip to Italy and get fitted for a Perazzi. Have a fun trip!
If you do, just don't watch what they do
They have a big shooting site in CA now as well, but I don't know if they do fitting there. When I was shooting All American in the 80/90's Perazzi used to fly their guys from Italy to the Grand and if you bought a Perazzi there they would hand fit it to you for free. Which is a great option, but it's hard to watch a guy who doesn't speak english take your 1 hour old beautiful stock, talk to another translator, and then proceed to start whacking away on it with a chisel and wooden mallet. Granted you came back in two hours and it looked as good as new but it's a hard thing to watch a brand new gun go through. What was fun to watch though is they'd have the woman doing the engraving there all day and watching her engrave things freehand was something.
As for the topic, it depends on your goals and your game. A 32" 34" combo might be great for trap, but not skeet/sporting clays. If you're serious about trap you'll want a single barrel option. That said for giggles I've shot my 32" barrels in both skeet, olympic, and sporting clays and did fine for fun, even placing at the OTC for Junior Olympics. However you'll find that if you get serious the length, balance, POI, fit, stock offset/butt pad angles etc. are all going to be different to be ideal for those different sports.
Honestly these days there are so many good cheaper options that also have adjustability to me the biggest advantage to the "big $" players is durability. A good example of that is when I was shooting competitively I wore out the hinge in a Citori in 2 years, Browning tried to reweld it but it didn't work, needed a new receiver. I still own and shoot that Perazzi I bought in 89'. Also realize that shotgun sports are a social status game, these days a trap gun, good barrels, durability, chocks etc. isn't rocket science, Browning, Beretta, etc. can all make great guns if you are not running tens of thousands of rounds a year in them.
I guess what I'm saying is that if you told me today that I wanted to shoot trap, skeet, sporting, olympic, games and I had the choice between having one $15k Perazzi setup for one of those games, or a compromise between all of them, and 4 Beretta's that were set up perfectly for each of the sports and I was not shooting say 25,000+ rounds a year, I'd take the 4 Beretta's every time.
Also beyond that if you have not decided on a discipline, buy a nice 30" Citori/Beretta etc. don't spend over $3k, then take it to a good gunsmith and have them fit it to you. In a year you will figure out what game you really like and you will know how that 30" gun works for it (too light, too fast, too slow, wrong balance) and you can make a much better purchase decision when you drop the big $. I can tell you I've known a
lot of guys that are getting into clay sports the last 30+ years, spend big $, and almost every one of them ends up switching guns in a year or two anyway because they didn't know enough to make an informed first purchase.
At the end of the day it's just like long range rifles, how many guys come into the sport, spend a ton of $ on a setup, and figure out in a year or two it wasn't what they really wanted/needed. There's always going to be some factor of "buy and try" in shooting sports, but the trick is early on when you know the least about what you want/need to minimise throwing $ away.
