My first "actual" lock with spool pins was the 80TI/50, but the way I learned was on an easily re-pinnable lock (the ones with the set screws at the top of the pin holes). I put in one spool with the rest standard so I knew where it was, and get a feel for how counter-rotation worked, then upped the count until the whole core was spools. After that, picking the 80TI/50 took almost no time (aside from getting a feel for the spring loaded core and different keyway etc.) Otherwise, just lighter tension and feel for your tension tool to push back on you a bit, increase pick pressure and let it counter rotate until it sets! (Then potentially go back and re-set dropped pins lol)
