If I have two (say c-system 4.5) balls drilled exactly the same but different surfaces, what difference in length (ft) would I get for the below surfaces:
1.) 500 vs 4000 polished
2.) 1000 vs 4000 polished
3.) 2000 vs 4000 polished
4.) 4000 vs 4000 polished
5.) 500 polished vs 4000 polished
6.) 1000 polished vs 4000 polished
Thanks a lot for your replies...
