The only way a whisker biscuit will work is if you use safety slides. I would not use any kind of site other than a epoxy rest if your tying to the back of the arrow. I personally tie to the back, you will get mixed emotions on this from others. When it comes to reels I will choose spincast 99 percent of the time. Main reason being speed. We fish a lot of tournaments and getting fish in the boat as quick as possible can mean the difference between winning and loosing. The retriever will do a fine job but not as quickly or as effeciently. I pick the retriever for shooting gator gar and thats the only time unless I was going to be going after sharks. No sights, its more of a hand eye coordination. Most of your shots are going to be fairly close to you so sights arent needed. For any more info Id need more info like are you gonna be shooting day or night, from the boat or bank. You can also check out bow.fishingcountry.com

Know your target before you pull the trigger.
