Probably the most sensible comment on this thread, Dorian.
If weight and ultimate strength had been my only interest when buying rims I would have bought 18" forged. However, my primary objective was aesthetics (wheels that I like, not anyone else) and durability as there was no possibility of me wanting winter and summer wheels and I drive my car every day (hence I didn't want a lip). I would have liked Volks Progressiv TEs but there was no way the budget would stretch. I did my research and came up with an informed decision. I was well aware that they were expensive for cast wheels but they fitted my criteria perfectly and were from a reputable manufacturer behind many OEM wheels. Thus to me they are worth what I paid for them.
Others like Rickya, Max or Lomoto also made informed choices based upon their own criteria, price being one.
If the spokes bend or snap because I didn't buy forged I will be the first to post here as a warning to others. However, I don't see a ton of posts on this or the other Zeds sites complaining that their cast wheels have buckled in normal driving.
