100-150 Feet is only 33-50 Yards. You can do that with most medium size casting reels. The problem with most level-wind Abu style reels is that the drag is to small for sharks over 4'. Don't get me wrong, there have been people that have caught sharks over 5' with a 6500 Abu but the drags have been toast after the fight.
If you look into the Daiwa SHA in the 40 or 50 you won't go wrong.
Practice on your casting and the distance will come...
