65° that's not too bad but it's better with 80° Leds ...
SFH487P are +/-65° (130°), SFH485P are +/-40° (80°). So SFH487P are very wide angle and will be consequently slightly less bright, (2mW/Sr vs 3.15mW/Sr) but should be fine for Freetracking.
Edit: SFH487P are only 3mm diameter, Freetrack works best with 5mm leds.
