I don't think anything in the current Storm lineup is real close. I know you're posting this in the Storm forum so not sure you're willing to try 900 Global. But, the Dream series is poured by Storm at the Utah plant, so at least it's got Storm technology in it. From what I'm told the Dreams are using a cover that is really similar to r2x. I have the Dream and is real similar to the Gravity Shift so this assessment seems legit. That being said the Dream On from what I'm seeing would be real close IMO and I'm being told that is the case. I think that would be the best option if you're willing to try that. Next option IMO might be a Sinister.
