Tips wont tell the story, apples and oranges unless the martin is that much different than a Hoyt. Other than the bow and we're different I've done it. You may notice a slight rise in impact point is about all that will happen. Make the rear end lighter and you might not even notice that. Those heads do a lot of steering. I'd go with the 100's unless I had the 125's. 100's aren't 100 anyways 106. 125's are 128. Shot'm if ya got'm.

That's my .02 You my find I'm way off but like I said, I've done it. If I changed I'd try something different like a Magnus. You might be able to find some used 100's.
