I have read a few threads that suggest certain calls have the edge on others. I did not get out as much as I would have liked this rut but I have called 3 bucks in to two different calls. First buck I set up in some woodland and after 20 mins of calling with the buttolo (starting with contact then distress/agony alternates) buck entered wood 20 yds from me and started raking the ground with hooves and antlers. Second two I shot 2 days ago using the nordik. 20 mins of contact distress nothing 1 minute of agony and a buck came hamering in, hour later from same seat a buck came slowly towards my possition (assume he was coming to call, didnt put him off anyhow).
Comparing notes with friends it would seem there is no real pattern to what works best. One friend used the buttolo on a buck he could see and it didnt respond then a couple of pheeps of the cherry wood had it charging in.
It would be interesting to get a concensus opinion from the members that use multiple calls as to what works best and when. I realise there are a huge amount of variables but you never know some pattern may emerge.
