Sorry if I came off as rude in my last post...

I have had a OS46AX and now a Saito 56 and both haul that plane around well.

I think you will find that either of the 4 stars mentioned will be just fine to see, but I agree the 4* 60 will be somewhat easier. I personally found that going from the XE2 to the LT-40 then down to the 4* 40 was not much of a problem. For me by the end of the first flight I had become pretty good at spotting the 4* 40 and keeping orientation and that is will Sunglasses that are perscription and Bi-Focals to boot. I have found Yellow works well for me. On mine I added checkerboard to the bottom of the wing.

I completely understand the desire to stay with a bigger plane. But I would not do the EVO .45 on the 60 myself SIG states a minimum of .60 2 stroke and the EVO .45 although powerful would be way under power
