what are the best longboarding wheels i can get for my standards?1) carving2) cruising3) no sliding4) i like wide wheels not anything under 60mm and what does like mm and like 78a or 83c mean?thank you for your time.
60mm is the size of the wheel's diameter. You might want to go up to 70mm or so. 78a is the hardness/softness rating. A higher number gives you a harder wheel. For grip and carving, 78a sounds good to me if you can find it.
copper pipe is not priced by the sq. ft., you will have to do this for every pipe diameter.
Copper prices change weekly it seems. The cost from a plumber will change as well. You can ask for a certain diameter pipe per lineal foot and most will quote you.
Copper pipe is priced per foot or length of pipe (10' or 20' length). Price changes continually. hard to figure what a Plumber would charge since they don't sell the pipe without installing it. Thats where it gets expensive. Also depends on the pipe size (1/2, 3/4, 1 or larger)
