2016 is a 531 spine and goldtip 35-55 is a 500 spine they are a little weaker. They are close you can tweek the gold tip by making it a little shorter or reducing the tip weight to get the correct spine or they may work just fine like they are.    Widow

The gold tip arrow is a little stiffer then the aluminum.

I've found 1535 with 200-225 works well with my 45@28(I draw 27 ) recurve  and my 54@28 long bow. For my 52-55@28 recurves 3555 29 inch with 225 works better. I foot all my arrows with 2117 1 inch(12grains) for the 1535s and 2 inch(24grains) for the 3555s seems to work for me(adds some stiffness to the shaft) I also play with different inserts to get the weight I want,   11 grains that come with the shafts, 50 grains brass and 100 grain brass, the new longer inserts for gold tips (long 50 grn) should act as an internal footing to stiffen the shaft(but not on hard hits) I would still suggest footing on out side to make your arrows tuffer on impact.(2117 for 1535,3555, 5575 needs 2216 for trad shafts )
