You can piece together simple or complicated figures EXACTLY the way YOU want to practice them...and it is EASY to do.
Frankly, I dont have a lot of free time. I have to choose: practice, screw-around with my kit, or figure out software. I like all of it...but I love to play. I look for any advantage that gets me to the fun stuff quickly!
I have been shedding Swiss-trips/hurta/blushda/single-stroke blushda and trying to get my feel right going in and coming out. I was able to program quarters going in then a measure of blushdas and eights out...the setup took me about two minutes. Then I started playing. Wow.
