It has been mentioned that the low gear ratios have caused the GNE B9's on the TTX to have a bit of trouble on the A19 but they haven't done too badly and have done way better than what any other 'modern' bus would do. As long as the oil is regularly topped up and they're well looked after, they'll do as well as what the DB250'S have done on the X18.
On another note, how did the VDL DB300 trial go on the X93? I haven't heard any opinions yet but in my opinion, they probably would've coped OK despite having the same engine as the E400 due to the lighter bodyweight of the Gemini 2. I strongly suspect that winth the imminent order of B9's for the X18, the 4 VDL DB250's will either operate the X20 or they will make up the 4 vehicles at Whitby to operate the X93.
Again, as we don't know an order date for the Volvos for the X18, we don't know what they will be. Although each Europe-based manufacture can still built 200 Euro5 vehicles this year, it all depends how many orders had already been placed for B9TLs this year it could end up being B5TLs.
The DB300 has proved to be superior to the E400s, and likely (due to them being ex-London) the B7TL/Geminis will likely end up also being trumped by the DB300. As for the DB250s, they are well and truly knackered hence their recent use on local Ashington work only - so likely they'll remain on services such as the 30 34 and 35/35a, maybe escaping onto the 20/X20 every now and then (although I can see the 20/X20 becoming the home of the older E400s alongside the 14/X14).
