Quick question. How hard is installation? I decided to drop both kits in my POL. As soon as a payment I'm waiting on goes through, gonna grab UW Ruination (who I hope also gets a kit in his colors) and ship. The other day was my first experience with a more intricate add-on kit (X2's set for LG Magnus), and I was pleased with how painless adding it was. Is this kit similarly easy to work with?
