I am writing a search strategy for a systematic review protocol following Cochrane guideline. Can I rely on SIGN/ BMJ search filters for RCTs in the search strategy? Is one better than the other?

If you are following Cochrane style, I suggest you use Cochrane search filters for RCT too: http://handbook.cochrane.org/chapter_6/6_4_11_search_filters.htm

Not sure why you would wish to use SIGN/BMJ filters when the appropriate filters are those with sufficient specificity/sensitivity to weed out what you don't require. The advice given by Farhad is exactly correct
Thank you Farhad and Zbys.
I have got the SIGN filters ISSG (from https://sites.google.com/a/york.ac.uk/issg-search-filters-resource/home/search-filters-by-design). The Cochrane filters are based on the ISSG recommendations. The reason I thought of using SIGN filters as my SR involves RTCs and Observational studies as well. And only SIGN filters are designed for different study types and databases.
Alternatively, can I use the Cochrane in the first place and if not available use SIGN/ BMJ?
