3/8oz is way too light. You need a tiny Bass baitcaster to move that well. Get a Tady 45 that you don't like, cut off the hook and head down to some local football field. If the Newell has good free spool and you can't huck that a mile on your 8' jig stick its on you! If the Newell has bad free spool you need to crack it and get some oil in the bearings etc.
