Yea I don't have money to throw down the drain either but a buddy of mine wanted my ISCs so I sold to him and got the GPs. I have another bud that has the GoPowers and he said they're incredible. Not one single noise and they are comfy when set soft and perform incredible when set stiff. Did I mention they're quiet? The ISCs are so clunky and noisy that I feel like Fred Flintstone and my wheels are made of rubble.Awesome man I need to get some new coils asap and I'm having a tough time deciding on what to get. I was gonna go with the ISC's but they seem to have some issues that need to be worked out. I don't have money to throw down the drain and that's why im looking to hear reviews for these.
