i have the hpv secondary with purple spring and a 44* helix. if i use the 160/350 primary spring, wont that keep my engagement way high vs using a 130/350? right now ive got a 100/320. (ps. this would be for riding in the mtns) is there an advantage to having the higher engagement? i would think that a lower engagement in the powder would allow a person to move around without trenching, so im looking for some ideas on this. thanks
