I think what we did was;
stage races - 2stages
GT - 4 stages.
Picking the best stages- i.e zoncolan. I think-if memory serves me right- we usually did a sprint stag, 2 mnt stages and a punchy type stage.
cobblestones made an interesting suggestion with a joker rider, up to you what you wanna do tho.
As for races, I suggest doing mainly the PT races. And maybe one or two others if you really want, again whatever you like.
