Pika shoots as good as the other two, arguably quieter than the other two, but the Elk and Shrew (OLD Shrew, Coffey or before) are a little more critical of tuning for sound/silencer type/placement IMHO. Elk/Shrew might be a tad zippier.
I'll be frank, with Dan Toelke's average 6-8 week wait honestly it's hard to not go with the Toelke in my book. I love Gregg and his bows, but I just can't do a 1 year+ wait if I can't either buy a spot or sell it if needed. Now if buying used that makes things more flexible. I really enjoy all 3 bows mentioned but am always on the hunt for more riser mass, so I currently have a 3pc 56" Hill Country Bobcat and it's everything these 3 bows are, just more mass. Roman also just released an even more compact 3pc bow, the Badger.
