The other thing I'll point out is that if you have the cliffy on Disaster Drop that might cause a fitting issue. I never bought that Cliffy but I did notice that it wraps around the end of the ramp and I thought that might take up too much real estate in that area. The way the Mantis fits in there, I'm not sure the Cliffy does much to add extra protection anyway.
Pretty bold to "point out" an issue with my ramp protector in one sentence and immediately admit you've never even bought my protector in the next. Wow. As for your last sentence all I have to say is look at the pics and then tell me it doesn't add anything.
