I of course cannot speak for you local considerations; price, avaliability customer service and so forth but as far as the actual product goes the entire AX series are clearly superior to their OS predecessors as well as the current bottom line OS engines such as the LA line.

If you are able to afford the differance in price then the AX is well worth it for the new or experianced flyers.

Not withstanding the ABN versus ABC debate I feel that the cylinder sleeve/piston materials technology of ABC offers no real advantage at all for the majority of us in the way we use our engines. The entire AX line are truly great engines and the newest of the AX's (.25, .35, .75) with the improved front slanted needle valve that uses a different type of mid range needle is even better yet. Thats not speculation but actual extensive use of both by myself especially in the smaller sizes.
