My teenage son is in the market for a pair of Frogskins and prefers the LX model. I notice that they are quite a bit more expensive in stores and online. I honestly don't see much difference but I'm a newb so what do I know? I'm looking for opinions to see if its worth spending the extra money for the Frogskin LX over the regular Frogskin (which I've seen for as low as $39.99 recently). Thank you.
