The madhab of the messenger of Allah? the later imams (ra) were learned men who did their best to interpret for us, i believe we should take what's good from their knowledge and use our intellect based on what we have of the Quran and hadith, but we should not identify ourselves based on sects, there is only one Islam.
Talking about the thirteen rak'at in witr, at-Tirmidhi says:
"It has been related from the Prophet that he would perform the witr prayer with thirteen, nine, seven, five, three rak'at or one rak'ah."

I respect anybody that may have a different opinion, but that's the conclusion i've come to
witr i take it comes from the word watr - odd.
so any odd number would do, not sure about one though, but i still think one is better than none.
