Here's a tip: When you remove the film from the paper, leave the tape on the film and fold it over the film edge -- this gives you a more secure starting point. I like stainless reels. Before loading, I have them all properly orientated so the correct load side faces right. Tmax is a lot thicker than Tri X, and is usually much easier to load. I often get the marks you have, but only on the first 1/2 inch or so that goes onto the reel. I'm very conscious of not bending the film past the first 1/2 inch. For the beginner, I recommend they use one roll for practicing.
