I hear a lot of talk about getting different shaves from changing the combination with different razors and blades. I have been DE shaving for about 8 - 9 months. I have bought sampler packs, and a hundred blade lot of both Astras and IPs. Astras have clearly been my favorites. Over the last 3 - 4 months I have bought 12 - 15 vintage Gillettes, adjustables, techs, superspeeds, etc. This week I have been using a gold tech I picked up at an antique mall a couple of weeks ago. I have been using the IPs. The shaves are terrible. This morning on my drive to work, I looked in the mirror and wondered if I had even shaved. I'm about ready to give up on the IPs. Is there a razor that I possibly have that would work better with the IPs? I know the tech is a mild shaver, but the shaves with the Astras were a lot better even with the tech. Any suggestions? Thanks.
