I shoot Spilit vision and instinctive.
I belive very few people shoot gap in the manner described by people like Rod Jenkins.
I do very well in local competitions because I don't get very involved with aiming methods,I just know what works for me and I do it.
I use bino's on targets when their allowed,their not for helping with range estimation,their so I know exactly where the 20 ring is.
Knowing exactly where it is helps me a lot in picking my spot,,,guessing where it is doesn't.
I've spoken to hundreds of die hard instinctive shooters over the years,,,they all seemed to be more interested in the process,rather than the end result,,,,I've never understood that.
I've had them try the old "hunting" line on me,,,until they find my hunting success rate is very good.
That old hunting/target thing goes both ways,its not just good target shooters that can be very poor shots on game.
I've been both a hunter/target shooter for over 30 years and I think I've seen it all as far as missing animals is concerned,and the aiming method has "nothing" to do with it.
In fact I personaly belive aiming,weather it be instinctive,split vision or gap,,is one of the lest important elements of any experienced archers form,,,yet perople still make a huge deal about it.
I say that because I personaly don't think about aiming at all,everything I do revolves around executing the actual shot well,aiming just looks after it's self,as it should,I've done it a million times at every distance I can shoot at.
About the only concession to aiming I'll even consider is that pure instinctive works very well at short ranges,while split vision works over all ranges,,,,,,just like Howard Hill said so many years ago,an I ain't arguing with Mr Hill.
