It depends on what type of music you are into, and whay type of rider you are. Eg1. You are a mad type of rider who likes to go big, (Gaps, drops and do thing unexpected), Then you would proberly have some thing with a faster tempo and a bit wackey. Some thing like 'Obscure by Dir en gray'. Eg2. If you are a chilled rider who is smooth and sweet then, you would have something chilled. You would use something like 'Lazy by X press 2' This is what I think and I did go a bit crazy with the examples. But I want you to have a good idea with what I think. I hope this makes sence (its does in my head.) DMC
