many companies have tried to bring back urethane reaction but have the carry and hitting power of todays tech. I have thrown most of these urethane hybrids and none have achieved what 900 Global/AMF have achieved with the Cobra and Bullwhip. I never have the opportunity to play right of 15 on any house shots unless im throwing plastic and carry is poop. But with the cobra drilled at 5 x 4.5 sanded to 2000 and shined has allowed me to do just that and carry well.
