Buying my first longboard (skateboard, not surf)? need help?

Wheels wise i would say to go with anywhere height wise in a 72mm to 75mm reason being AWESOME CRUISING ANS SLIDING SIZE. Then as for durometer you got 73a to 101a to choose from so depending on what your going to be doing. Lets say your going to be doing more cursing/carving then on bad road condition/sidewalks i would go with a duro of 73-78a because they roll over absolutely anything. If you have better road conditions then go for a little bit harder duro like a 78-83a! I hope this helped!
