Just get enough rof.
I bet he can't do that to a goldenball 0.4g! They are like small stones, I couldn't get a clear cut with scissors, so I had to file it to see if there's any voids, and I couldn't spot any. if you can't get bioval 0.4g, get goldenball. Still need to do some tests, after I get my vsr running.
I should become a salesman...
