I can't comment on the 60 size from flying experience, only that the color scheme makes it hard to distinguish top from bottom. I've got the 40 size with a Saito 72 and it's a blast to fly. Probably becoming my most favorite airplane. I just acquired the 120 size for a ST3000 I've got and if it's half as fun and good flying it'll soon become another favorite. The engines you've got listed would work accordingly with their respective size planes and I haven't seen one of the Ultra Stick's yet that didn't fly beautiful! I guess it's mostly gonna be a matter of preference on your part and I highly recommend any of the above.
