Bow is a 54@28 Toelke Whip (R/D longbow), drawing about 27.5 and like and arrow about 29" bop (125 gr. point).

I'm thinking the 2016 would be a better place to start, but been second guessing myself...

i would say 2018, the next step up from a 2016.

2016 = 50-55# spine
2018 = 55-60# spine
2117 = 60-65# spine

2016 is a good start point for that bow with that point weight.

I agree with vermonster13, the 2016's are what I sometimes use out of my shrew bow

2018 should work good

2016 is good start. I would consider 2018 as well.

I use 2018's cut 29" BOP out of my 60", 55# Fox, "Artic Fox" LB and I draw 27 3/4". They shoot great and carry a little more weight than the 2016's.  I use a 125 gr. vented magnus or a 145 gr bear SS razorhead.  Can't see any differance in the way to two heads fly.
