I fished the 6 inch Magdraft (pre-rigged version with the magnet) this weekend.  Looks awesome on Chris Zaldain's videos and my buddies at the tackle shop rave about it. For me, about every third cast it wouldn't swim straight. Naturally, it is on the times you make that pinpoint cast. The magnet isn't doesn't hold it in the center all the time.  I was constantly haven't to fiddle with it. Anyone else have this experience? Should I just switch to the Freestyle version and rig it with a Flashy Swimmer. 

The Magdraft is very finicky about retrieve speed. You really have to concentrate on finding the right retrieve speed with them or they will not swim right. The freestyle is much more forgiving being that you are generally fishing them keel waited which keeps them swimming the way that they should at almost any speed. 

I have 3 of them in the 6in size and they have been great.  You have to find the correct retrieve speed.  Too slow, it doesn't make a ton of motion.   Too fast, it turns over.  So far it has been the soft plastic swimbait I have used.
