About the Bag:
The ALL NEW MK-R is dynamic. The MK-R fast-side material is quick but controllable. Speed can be compared to the Viper-C. The increased grip provides players with the confidence to attack the hole on push shots and when trying to get through tight gaps. The slow-side comes from our Viper-R and is the hottest fabric in the game. Break-in on this bag is minimal as this bag delivers great flex out of the package. Minor stretching on the slow side should be expected as with all hybrid carpet, but the mid-sized template accommodates for this and leaves room for multiple break-in methods. For fill, the MK-R has our unique Tribrid™ fill. Our new glass pellet enhances the MK-R’s ability to be cut and rolled. The MK-R is set to be a very useful bag for players of all skill levels.
Speed Rating: 7/5

- Fast Side Speed Rating (Hot/Dry): 8
- Good Speed. Not too fast. Great in hand feel.
- Slow Side Speed Rating (Cold/Damp): 4

- Slow Side Speed Rating (Hot/Dry): 6
- Quick, but a hole magnet.
Looseness Rating: 8
Great forgiveness and a hole magnet. Has a great feel in the hand. We suggest using our 1-Hour Break-In Kit to accelerate break-in. The template size is optimized for playability and collectability.
Durability Rating: 9
One of the most durable bags we’ve ever produced. However, the fast side may still snag. The fibers of the fabric are super strong and when they catch onto an edge they pull out of the fabric instead of breaking. This will not cause the bag to fall apart but it will look like a line in the bag. We do not warranty fiber pull outs so be sure the boards you play on are smooth on all edges.
About Speed Ratings: Speed of bags is strongly dependent on the humidity level and the type of fabric. Cotton or duck bags will generally be very fast in hot/dry conditions and slow in cold/damp conditions. Synthetic fabric such as polyester will play much quicker in cold/damp conditions and is generally more predictable. Speed rating of “0” means the bag is so sticky that the bag will not move even when the board is tilted at a 60° angle. Speed rating of “10” means the bag will slowly move down the board at regulation board angle of 11°.
About Looseness Rating: Looseness is based on the stiffness of the fast side fabric. A tighter weave will generally produce a stiffer bag. Looseness rating of “0” means the bag is very stiff and is highly likely to clog the hole. A Looseness rating of “10” means the bag will slip into the smallest opening if the fast side speed rating is high.
ALERT!!! If you boil or overheat your bags, we will know because they will have shrunk!!! You void your warranty if you overheat your bags!!!
Be smart and use our 1hr Break-In Kit instead.

It is a bit of a slower bag. However, it feels perfect in the hand and that encourages you to throw it. I prefer slick side down and it does play like a 7. The sticky side is definitely a 4.
