I'm with Luke. I haven't shot the wrath so I can't compare them directly but I can say as an Ion owner that for under £200 than are more than you could ever expect. The eyes work brilliantly, it cycles fast, and the whole package has a great feel and balance.
I can't say definitively that the Ion is better than the Wrath, but I can say I couldn't care less about the extra 3bps, and the field strippable bolt doesn't bother me that much and I love the Ion styling so for me, it's very much the devil I know...
