still being new I didn't/don't want to spend a million $ (which is ironic at the rate I lose $5-9 lures)...my crappy herters waders were a lot of fun in the summer. I'm having a hard time figuring out how warm/thick I need for fall? I don't want to melt when it's cool but not freezing and I don't see wading through slush/snow. what thickness/insulation level would you recommend? any particular less expensive ones that you think are fairly good?
