I just got a used 58" Whistler with the standard grip, thumb rest, and I am so happy with the way my hand just locks right in place on that Toelke. I do like it better than the grip on the Kota Kill-um that I parted with which is a 50's style recurve with more of a classic longbow type grip. I've never shot a shrew so I can't say anything about them but I'm really liking this Whistler. I should also note that I have a take down Whistler model with the bow bolt that Toelkes use and I like the slight bit of weight it adds to the riser.
