they are the most effective option at long distance, when CVs jump to 2000, or for internationals, when HVs are 1500 and CVs are unavailable. not counting scholarships and promises, that is. under 1400 miles, CVs are the best option, until you get close, and then its HVs (how close exactly, its hard to say). and of course, with calls/letters capped, they are only the best long-distance option for a little while. particularly, they should be used by d2/d3 schools at distance. theoretically they should be used over evals in pulling players down over 360 miles as well, but WIS artificially reduces the effort you get for pulldowns, and im not convinced calls/letters are reduced in the same manner as evals. ive never thoroughly tested but i have had some strange data points that didn't fit the bill if the reduction was the same - however, we know it takes more effort when others are going after the same guy, so i don't have definitive evidence either way. conceptually, i would say use the calls/letters, but in practice i don't know that's right.
in practice, calls/letters are just not very useful in d1 anymore. it was quite the racket when you could use letters only for internationals, unlimited, and just about nobody else knew it. i was pretty bummed when that went away. it gave you TWICE the effort as your opponents, for the same amount of money (roughly, not taking into account prestige). i once poached A+ UNC who had like 30k more than me as B+ south carolina, for an international, after they took a local off of me. it was pretty glorious.
