Good luck in your homework; As I have 2 current EAB's, I also may be seling my 601XLB later this Spring-not having time for two + moving this Summer. Some preferences in the 601XLB which I did or to consider w/ the one you are researching: you will find a few of us reversed the gear. This keeps the nose off the rnwy much longer on landing + perhaps a little more elevator longer; I did the dual stick option + prefer this. I painted the glare shield flat black-no canopy glare; also painted the back of the Sensenich prop flat black-no glare-balanced of course + consulted Sensenich in Plant City before doing so; tinted canopy vs. clear my preference; built lower cowling lip extension to get air out + extended the dbl. exhaust also, as it also keeps the belly clean; insulated the floor, side panels + turtledeck w. lt. styrofoam before air link carpeting, so much quieter + warmer; added a full length elevator trim vs. the short standard one, retrofitting; many other upgrades while doing the 6ZU1-6ZU6. If inclined, what is he asking-perhaps this will assist me in a market price. I may keep my high wing , although slower, due to knee ACL skiing, bindings didn't release.
