30 shaves! Wow! I rarely go past 3, maybe making it to 4 when I'm lazy, but I best prefer 1 or 2!I just made my first 100 blade purchase I went with Astra SP. I got 15 of them in a sampler pack when I first stated this journey, almost 2 years ago. I've been very happy with them, been getting up to 30 shaves per blade with them. I was ordering a few things for the wife from Amazon, and figured what's an extra $10 for what should last me a several years.
But yeah, a lot of us start with Astra SP - for good reason - and then seem to stick with them or always have them around.
They're my goto recommendation for a newb: Dirt cheap and readily available from a multitude of sources, sharp enough, smooth enough, reasonably robust, and versatile. What's not to like?
