back rise measurements? my husband is looking into a new pair of jeans and likes the look (from online pics) of the straight sven and even steven/new ralf. he's looking for a pair of jeans that have a looser fit (already has skinnier jeans). i've been able to find front rise measurements, but what about the back rise? his current jeans are a 10" front rise, 15" back, and he'd like the new pair to fit similarly, esp in back. for reference, he's about 5'10"-11" and normally wears either a 31 or 32 in pants . . .
