Good question. From what I gather, most people think that Edges are a little more stable in 3d type manuvers (ex. a Harrier) than say an Extra of similar size. This is because of (I think) the straight leading edge. Conversly, the Giles' leading edge is greatly swept in comparison to the Extras', meaning (again, I think) it would be less stable in 3d manuvers. This seems to be correct b/c the few Giles at our field seem eager to spin (tip stall easily), whereas you just about have to force an Edge to spin. Anyway, to answer you question: yes, a Giles should be able to do the same manuvers that an Edge (or Extra or Cap, etc) does, you just may have to "get on the sicks" more and be more cautious.

Of course that's just my opinion...
