I prefer SMRT to switch to double deckers. 
Bendies cause a lot of problems to SMRT operations like space
and schedling issues. They cause a lot of jams and queues along bus
stops and bus interchanges and they take up too much space in
depots and interchanges. And they are more complex and costly
to maintain and is not suitable for our roads and harsh operations
here. 
Thus SMRT should use double deckers which many services can be
greatly improved without causing jams along bus stops and
interchanges and save a lot of parking spaces for more buses
instead. One good example is 190, and other services like 61, 106,
176, 184, 804, 806, 812, 851, 854, 857, 900, 901, 902, 903, 912,
913, 960, 969. etc.
Look at the number of services, SMRT can easily purchase 300
double deckers to solve their problems.
Not really true. Kranji and AMK can accomodate, only parts of the
Woodlands depot have restrictive heights.
Moreover, Kranji and AMK depot are slated for replacements in a
few years time. These depots are to be built to cater double
deckers. 
I agree. Double deckers are the way to go for SMRT. Many services can be improved using double
deckers. There is no space for so many bendy buses, especially in
future with more buses. No bendies.
But existing Woodlands interchange can cater double deckers,
look at 161 and 168. Current Yishun bus interchange will be
demolished soon for the new air con interchange built in a few
years time. So the temp interchange and new interchange are
expected to adhere to the new height restrictions (4.5 m) for all
bus infrastructures. 
From your note, it clearly shows that if SMRT wants it can
switch to DDs and it will solve a lot of its problems.
I hate it when 190s and 106s bendies on Orchard road create a
long tail of buses. Easily these services can be moved to DDs.
Similarly the 960, 851 at Bugis create a havoc.
The DDs can be parked at Kranji and AMK. I am sure it will also
be profitable for SMRT in long run.
There is no need to completely remove bendies from its fleet.
Bendies can be continued to use on feeder routes such as 804, 806,
911 etc. and may be on 67 due to height restriction on Dunearn
road.
A good mix of DDs (200#) and bendies can really be good for
people living in North West and profitable for SMRT. Are u
listening SMRT?? :)
