I've never shot a Savannah, but I do own a Tomahawk Diamond Series Desert Fox, 55@28, 52# at my draw.
And I own a Black Widow PLV, 46# at my draw.
Both bows are 64".
The Tomahawk is my "go to" bow. I like the grip and for whatever reason, I am more accurate with it.
That being said, the day I bought my Tomahawk, I had the opportunity to handle another one just like it only 62", the grip on that bow I did not like, it felt too big and bulky. I assume Great Plains doesn't use a CNC machine and the riser is hand shaped, I am not sure of that. The Tomahawk I did buy has a much more slimmer grip.
Hope this helps.
