Congratulations on getting your recurve. Fun, ain' t it.
Catwhiskers will do a lot to silence the twang. You don' t say what arrows you' re shooting, but arrows around 10 grains per pound of draw weight (500 grains for you, if you' re shooting it at 50 pounds) will help quiet it down too.
I like 2-blade heads myself, like Magnus 125' s or Bear Razorheads. Best thing I like about ' em is they' re cheap and work just fine. I' ve never shot ' em on a recurve, but I hear Muzzy 3-blades do good, as long as you hone across the flats of the point to get good sharp edges.
