In general, I think that most people with most things (like software programs), blades, etc. tend to like what we "learned on". Kudos to you for trying to learn a different way. I don't know that there is a right or wrong - it is usually what we find that works best for us. However, being willing to try new things/new ways new tools keeps us learning and sometimes we will in fact find something we like better then what we are using/doing. Other times, it simply offers us a new way to approach or do something. Win-win in that case. I still need to learn to master the blades I started with - flat - but those are probably best for Intarsia work anyway. One day I will attempt some spiral blades if for no other reason then to see the difference in how they work.
