Disabling 802.11a - good idea?

I've finally moved into the 21st century with an Asus RT-N66u router. I've set it to have 2.4GHz and 5GHz with the same SSID so that each client can automatically choose whichever has best signal. The 2.4GHz network is on "Auto" mode, which I assume means b/g/n. The 5GHz network defaulted to a/n, but I'm wondering if I should change it to n only. I don't have any devices that require 802.11a. Would disabling "a" provide any benefit?
 
I just use 802.11n for 5GHz and I haven't had a problem with any of my 5GHz devices.
I tend to use an SSID for 2.4GHz and an SSID for 5GHz.
The reason for me, was that my Android mobile phones tended to favour 2.4GHz(72Mbit) over 5GHz(150Mbit) and as I only use a 20MHz channel on 2.4GHz I was missing out on better bandwidth when in the same room as the router.

802.11a is commonly listed as a catch all representation for 5GHz. ie: 802.11a/b/g/n, which implies dual band.
802.11a provided 54Mbits on 5GHz

Don't think there is any performance benefit in using 802.11n only on a 5GHz AP, but on the same note, it doesn't hurt either.
