So just got this email from Tomas over at Latitude regarding the Spike and Sinus in premium plastic:
Spike will be made in Gold line during this winter, we've made a small batch of them this summer but ran into some problems so we had to stop. Since then we haven't had the time to make them, but they will be made :-)
Sinus could be made in Opto or Gold but we haven't tried that yet, so I don't know if it will work or not. But we will try the next time we will make them.
I hope you can wait for them
I can wait, I just don't want to :-)
