So I'm a beginner to Cardistry, and I've been using two types of cards, the Tally-ho Circle back and the Standard Bikes. I've used the Tally's for about 2-3 weeks now, and the Bikes for only a day. I find that the Bikes slide a lot more that the Tallys, and its easier to do cuts like the Revolution and Sybil cut with the Tallys. Is this because the bikes haven't been broken in yet, or are Bikes just more slippery than Tallys? Any help is appreciated.
