I doubt we will change the length for this model (the 125mm).
But we have in mind to do a 115mm that would fit the need of people who like shorter and lighter heads, this one could potentially goes to 82g (2g gain from the thinner walls and 6g in the triangle).
We may can produce 4 models:
cap: 115 / 125
uncap: 115 / 125
But about lighter and medium model:
In my opinion they have to be all as strong as the current model, because how can you promote a lighter/weaker model?
"lighter model for girls/kids?"
Maybe the lighter could be 60mm diameter ( http://poloschlaeger.de/
is 60mm for exemple) at this diameter it could be just under 80g.
We don't know now what will be our next step to be frank.
By the way, how would you call the capped one? Simple Cap? Simple Capped?
