A few comments from my experience.
Try shooting SKEET and Sporting Clays/5 Stand. I have always found Skeet shooters to be more sociable and more willing to offer advice/guns to shoot. Skeet because of the layout means all the shooters are in close proximity during the round, Trap has the shooters separated. Besides, Trap shooters are grumpy.
Try all the sports, you may find one more enjoyable.
Get a lesson first! Just because you are a guy and shoot does not give you expertise. Having a pro show you how to stand, mount and look for targets, and how to lead the target is a key to enjoying the sport.
If you like the feel of a particular O/U or SXS, take it to a gunfitter and have it fitted. Once you have shot for a time this will become apparent to you.
It amazes me how rifle and pistol competitors will spend thousands on equipment,sights,stocks etc for a gun originally costing under $1000, and shotgunners won't spend $300 on a fitting for an $8000 shotgun. Even pumps and autos can be "fitted". Beretta includes wedges with it's Clays Autos to allow alterations in cast and drop.
