mounting flat skins

I am in the process of mounting a flat skin(texas steer) on an LP Aspire drum(11 in.). When tucking the skin between the flesh hoop and the rim(comfort curve), I'm having a hard time getting the skin and the flesh hoop to fit all of the way inside the rim. I didn't account for the fact that the skin thickens upon soaking. My next move would be to look into getting another rim, one of the traditional ones with the V-shaped hooks. But I was wondering if anyone else on this forum has experienced this, and if so, what was your remedy?
thank you.
