Need to know your draw length and bow weight at your draw length, but I'll take a guess. Probably need to go with a 75-95s. Agree, you'll need to put about 250-300 up front. Easy to do. Start with a 100 grain brass insert and 150, 175, 200 grain point, etc.
I like to start with my arrow cut to length, i.e., one inch beyond the back of the bow at full draw, and tune with point weight and side plate adjustments.
If you're drawing 60# at less than 28 inches, will probably be able to use 55-75s.
