Yes it is a preferance thing.You can get a small steamlined grip on any of Bobs bows.You can get low,low/medium,medium or high wrist.You can get the grip custom made by sending in something to copy.I have grip on my Shawnee B riser that is unlike any other grip I have seen on a Morrison.Its like a Dale Dye but slighlty lower.
Some like the Shawnee and some like the Cheyenne.I have had quite a few of both the Shawnee and Cheyenne and currantly have 3 ILF risers that are like the Cheyenne riser and also a Shawnee riser.
I like the Shawnee paired up with carb/foam longbow limbs.Mines a B with E limbs.Its a great shooter especially for a longer draw in this configuration.The shawnee riser is more straight up and down vs the deflex of the cheyenne or ILF riser
The Cheyenne and ILF with the deflex riser is superb with recurve limbs IMO.
All the Morrison risers are very versaitile with the multiple limbs lengths available to mate to them and you get 3 riser choice lengths in the Shawnee or Cheyenne and even more length choices with the ILF risers.I got 15 inches,17" and 19" in the ILF riser and may try a 13 inch mini in the future if I want a really short brush/blind bow.
You get alot of riser material choices as well from all phenolic,phenolic/wood,wood or all diamondwood or actionwood etc.Or aluminum in the ILF
