I'm going to order a small amount of rock. I'm very new to the hobby. I've been hitting raw stuff from the area I live in and it's all very brittle and small. I've been hitting and flaking ceramic tiles. Any advice on what to purchace? From the video's on YouTube I'm thinking dacite is a good rock for beginners. I've decided to go with Neolithics and I'm wondering if I should get the Good, Bad and Ugly $25 flat rate...anyone familiar with this? Thanks for any help.
