I put 900 hours on a Warp with my first Model IV with no issues and the guys I most frequently flew with favored the Warp. I found while flying with some IVO guys that inflight pitch issues would occasionally occur requiring unscheduled stops to do field maintenance (two in one flight - both of the IVO equipped airplanes). The Kiev has great reports, but being fairly new, I decided to go with what I was familiar with.
Our flying group has flown all over the Western US - Parts of Washington, Oregon, Montana, Wyoming, Arizona, Utah and most of Idaho, Nevada and California. Terrain has included Mountain, high Desert and the coast.
