Well I know one thing; its pointless trying to nick his fish using the same bait!
I think both luck and feeding plays a big part too when talking about cruising shoals and opportunistic fish.
If they're right there in front of you in numbers then its anyone's guess as to who bags the most and every chance he could be buying the beers. :w But quite often you both end up fishing a likely looking spot and neither of you get a bite for ages so essentially your both feeding little and often and waiting, hoping, maybe casting around a bit to the left and right margins, far and near, essentially feeding several swims until you find the fish.
In this situation your only hope is to wait for a passing shoal to happen across your pile of goodies, the direction they approach will largely determine who catches first (all things being equal, bait, style of fishing, skill), unlucky you if your mate holds the shoal first because apart from snaffling the odd stray and solitary cruising fish it will be hard for you to muscle in and steal the show.
Clearly watercraft is important too, apart from having super power predictions and foresight or prior knowledge of a venue; I think its fair to say its pretty damn hard to determine which way the shoal will approach... the obvious gap between an island channel isn't always present on some venues and in vast open water.
Which begs the question, is it actually better to spread a
crumb trail of feed or continually feed several swims at once?
Over to you...

Ps Ive never fished a crumb trail before, I'm not even sure if there's such a tactic to be honest - just a mad thought!
