Rotala - Prestonbus

[NX Spectra 4001]

RE: Rotala - Prestonbus
Whether anyone can answer this for me, or not, but here goes:

Are the Hybrids rare on any route? As both today, and yesterday, I've noticed 40606 on both the 8, and the 31A.

I thought that the Hybrids were for the 23, and on Sundays, the 23/35?

Also, there seems to be a lot more Hybrid Versas on the 35 than the last time I was up here, as both today and yesterday, I've noticed at least one on there, whereas, last time I was up here, it used to be exclusively double decker operated?

Cheers for any assistance on the matter
