A choice of motorcycle pants. Help please.?

Hi, I'm just about geared up completely for riding. (Taking the MSP course a week from now. Though, I doubt I'll need full gear for bobbing and weaving around cones at 5mph. =p) Regardless, I got most of it now, well before I'll be getting my bike. My question is which of these pants would you choose?http://www.motorcyclecloseouts.com/s...+silverI'm a thin guy, so sweating shouldn't be too much of a problem. However, I do get colder a bit quicker than someone that has more meat on them. Is the leather protection so superior that it'd be better to take them? Or are the Fieldsheer durable enough that I can enter comfort into my equation. Also, my limit is about $150~ish. Are these good deals? My jacket is full leather, if you're curious. I chose silver for the over pants as my jacket and helmet are silver.Thanks for any helpThanks guys. Got the Draggin'jeans. They look quite promising, and I'm thrilled that I can wear'jeans'on the bike.
