The hard medium is the most consistant heel rope run after run with really good grip on the saddle horn when you dally.
Very durable great feeling rope. Stays open through your delivery and has the perfect tip weight.
Beat rope ever
From the time I pull the twist ties off and make my first swing to placing my bottom strand on the ground I have confidence in every swing.
I think the Thunderbird is best heel rope I have picked up. It does not fight with your hand, stays open under steer, is light and fast. At age 69, I tie on. I went to a round robin indoor last Friday, muddy legs on steers, literally wiping the mud off the rope after a run. I beat better heelers than me and won based on consistency. Since my first trial one, I have ordered 4 more.
