In my 2114 X7's I have the Easton 2114 RPS insert (25 grain) and Merlin's 5/16 Ballistic RPS screw-in points, which come in weights of 80/90/100/110/125 grains.
So these are definitely heavier than Easton's NIBB point for the 2114, which is listed as just 78 grains on their shaft components chart.
There's also the Saunders screw-ins which (for the 5/16 size) come in weights of:
·
Bullet points: 75/85/90/100/125 grains;
·
Combo points: 55/65/75/85/90/100/125/145/150 grains;
·
Field points: 75/85/90/100/125/145/175/200/225/250 grains;
but I've not tried any of these myself as I couldn't get hold of them when I bought my X7 shafts.
There are also some other brands/makers of RPS compatible screw-in points, but none seem to offer a wide range of weights in the 5/16 diameter needed for the 2114 shaft.
