Cole has a thicker and longer? shaft than the other 3 and due to size shuffling has about the same size knot as fenrir in most sizes. In fact fenrir is among the largest toy is each of its sizes, according to the website's measurements.
I have a Cole, Diego and Fenrir. They are all great toys in their own ways. Coles shaft, as simple as it seems is really good at rubbing ssweet spots, Well at least for me. And its knot in enormous.
Fenrir shaft is kind, meh. The ridges are ok for light teasing, but the shaft is just too short and thin to really do much for me. But damn is its knot amazing. It very abrupt and it locks very well. Fenrir is one of my favorite toys even though its among the smallest in my collection.
Diego shaft is super thick. More so in firm, the almost perfect cylinder of a shaft fills you up in a very wonderfull way. Theis makes the complete lack of textures is not really an issue for me other than it squeegeeing off lube. Diego like cole also does a great job of hitting my sweet spot. Its knot is lice as well, its only a little bit thicker that the shaft, but since its very spherical, so like the shaft it will find and press hard into sweet spots and the length after the knot is sufficient to tie well. The issue some might have is its length. I thick its a bit on the long side for many ladies to tie in the larger sizes (well all four of these toys). I could be wrong, I'm only an expert at backdoor play.
Hope this helps
