Preferred ads SDK to use on SlideME

Hello,

I'm trying to implement ads in my application.

I am confused as whether to use the SDK found here (which seems a bit outdated to me):
http://ads.slideme.org/documents/sdk/slideme-android-sdk-3.1.zip?utm_sou...
(which i found while looking here http://slideme.org/blog/introducing-slideme-ads-premium-mobile-ad-networ...)

or the sdk found here:
http://account.mobfox.com/v2/www/sdk/MobFox-Android-SDK-5.0.0.zip

More specifically, i see that the latter (MobFox-Android-SDK-5.0.0.zip) has some extra options such as:
mAdView.setAdspaceWidth(320)
mAdView.setAdspaceHeight(50)

which i would like to make use of.

Can you please advise me?

Thank you
