Nice. So you're on a medium and feeling good? Seems like the general consensus is run 150mm fork???If you liked your medium Insurgent, the Medium Calling will feel right at home. I rode my buddy's M insurgent for awhile before I decided about getting my calling and they feel very close. I'm also 5'10" and the good/bad part is that you can go either M or L a lot of the time. I would also say you nailed it about what the Calling is for. It's my "fun" bike. Still very capable and I'll take it on just about anything, but it's just not quite as fast as my longer travel bikes. Damned if I don't take the Calling out more often though...
