I got some samples from spike it and I did not like it at all. It was very strong smelling and gave me a headache that was something awful. It seemed a little different in a way that I cant put a finger on but I did not care much for it. If I was starting out new and got use to it first I might like it better. I seem to think like snake and say that if you are working with one that you like ok and are comfortable with, if it is not much more I would stick with it. Spike it is cheaper than the calhouns I use but I like the calhouns better. I guess a lot is personal preference. i used mf before too and I liked it as well.
