Definitely try out sample packages. Its fun to try something new. When I started a was hooked on samplers to try different blades. I've tried most of the common samplers, but still like to try new blades. Some feel sharper, some smoother, and some last more shaves. I once saw a guy post that 'you guys are nuts, they're all the same'. Maybe he was lucky, he can just buy the cheapest blades and be done with it! But he'd miss the excitement and anticipation of maybe, just maybe finding the ultimate blade for you, that's out there, just waiting for your face to discover it.
Yeah, a sampler pack was huge for me. Came away loving Bluebirds and Feather (blade of choice). Every blade was different, some much more than others. But, Your Mileage May Vary.
