^The thing is, if one person does a good spin in a difficult position and another person does a good spin in a "normal" position... perhaps the first person should get more points. However, if we make the GOE more valuable than the levels, it will encourage people to do the spin they are best at, since--in theory--they should earn more points with a good spin in a normal position vs. a bad spin in a difficult position. This is just the theory of course--like you said, in practice the judges might not be willing to give +3 GOE for a fast but basic spin.
Maybe something like this: one levelled spin like we've got now, but with GOE more important. One spin with only Level 1 and Level 2--to get level two, you need some amount of difficulty (entry, edge changes, position, whatnot) but you're not forced to do the flexibility moves. One spin that's basically the equivalent of the ChSt: Do whatever you want, scored only on GOE. The spin rules I understand less than anything though, so this is likely all unhelpful.
