The key to success to competition shooter is to never stop and try new drills, different stances and of course to experiment with equipment.
Benelli Supernova is a great shotgun but it has some things which can be improved. One of such things is slippery forend. It has groves but plastic is slippery, I wish I could get Hogue overmolded forend for my Benelli Supernova, I miss it so much.
By the way, this is one of things why I love my Rem 870, you can choose from hundreds of upgrades! Accessories for other shotguns are very limited.
