was playing around with the HC weights last nite.Put 5.3 g in the heel.This is good for approx. 4300 engagement according to the instructions.Put 3.3 g in middle hole and in the tip for a total of 6.6 grams.If I would want to be heavier on tip,could put 4 g bolt in there for a grand total of 7.3 g.Of course I cannot try it out for a lack of snow these days...lol.Will not know anything until snow comes around again,but am anxious to try the heel clicker's out.I guess I'll have to grind some of the area on the movable sheave where the heel will contact when the weight is fully engaged.Also will have to grind the washers on the heel so that they do not screw up the 15.6 rollers.Would it be recommended maybe to go to a smaller roller so I won't have to grind them washers.I know the weight is designed to work with 15.6 and no larger roller,but also a smaller roller could be used,but what advantage would that create?
