Yo Bob...

There is a line somewhere, which after crossing I will have passed from helpful to PITA. I may cross that line here, but I mean well. Bear with me please.

Why in the world would you deliberately limit yourself to the 70? There are no advantages that I can see to owning a 70 vs an SS. Maybe it's quieter or something?

My vote (not that u offered me one) is that if u are leaning toward the Wren brand, get the SS. More thrust = more options later. Virtually same $$.

If u don't require a Wren brand motor, the the Rabbit and Merlin offer more options still. I'd hate to see u covet an airframe later that u have to pass on due to a lack of ponies under the hood, my jet brother !

(Then again, perhaps I've missed something obvious in the 70's favor ?)

Sorry, I know it's none of my business and I don't mean to nag...again, I mean well !
