But out of the two you mention yes i would go for the Original 506, so long as it is working properly.
Little bit of advise on setting the handle in relation to where the spool is (inside the bell or back out of it)
Remove the cowl just twist to the left and it will come off, now you will notice the Spool and line, turn the handle until the spool is backed out of the Bell, this way the angle of line release is correct, when it is inside the bell there is to much of an angle for the line to release smoothly and will hinder a nice cast.
Ok now look at where the handle is, if it is towards the twelve oclock remove it (just the Handle) and move so that it is facing down, and replace the large screw/clutch screw that holds the handle on, for some reason it is easier to remember to point the handle down when casting, and this is roughly where it ends up anyway, so if it is down and the spool is inside the bell housing the gentle under harm cast will be hindered.
Hope you can understand what i am trying to say here lol
