John you will love the 4. Mine is basically the speedster with dihedral in the wings because it was once a long wing. I have the grove gear, 27.5 tires and the T3 with 8inch wide matco in the back. I have electric trim in the elevator, but what's really nice is the 912uls. I stop all the time at 300ft if the grass is wet go to 400. the grass at my airport is super smooth and they water it every morning at 5. so by the time I get out there and fly it's super wet. which can be fun also.
