It's going to have to be your call.

It seems a lot of your options are based off your pt hub. So I would ask yourself if you need it for racing. If not, keep the hub you have and use it with a good training set. Since your rear is still rolling you only need to get a front built to go with it for now. And then look for a light weight race set.

But if you think you need power during races then figure your best option to get it: lightweight Pt wheelset or quark or vector. Sell and buy what you need to to get there.
