Newbie looking to get into fly tying and I'm wondering if there are any differences in vises for a left handed person? I'm looking at a Peak or Danvise to get started and I noticed the Danvise has parts included to change it to a left handed model. Is this an important feature or just a minor adjustment that left handers are used to making all the time? Any left handers out there to chime in and help me out.
