I just ordered an Adrian Page 60 size Gee Bee R2. He mentioned that this plane was designed for a Saito 91. I am having a hard time deciding between the Saito 91, Saito 100 and OS 91. I am leaning towards the Saito 100 since it is less than 1oz heavier than the 91. Any thoughts on this combination? Any suggestions on considering something else? Thanks in advance.
