Some guys like the side saddle, some don't. I would recommend putting the velcro base on it and then you have the option to stick it on quickly shoudl you need it. It comes in handy on an all shotgun stage (or match) when you have birdshot, buck and slugs all on the same stage, and you have to transition back and forth between all three loads. At minimum I'd get the two shell holder that goes on the forearm. If you miss a target or misscount reloading or drop a shell, its nice to be able to keep your weapon shouldered, reach forward, grab one shell and just slide it back, hit the button and fire off that last needed round. And put on some type of bolt release cover of your choice.
