PureGro1: you see very few top tier players who consistently post low scores with a hybrid in their bag.
review the scores being shot with the etour SOTW clubs... 2 wedges and a hybrid included. it can be done.

the more plausible reason why most people dump the hybrid is because WGT did not gap it appropriately with other clubs. as such - a hybrid is basically redundant yardage to a 3i with the higher level equipment.
players can play with 2 wedges, but using 3 becomes even easier and reduces yardage gaps which can add more precision- especially since there is little incentive to keeping a hybrid that will play similar to your 3i.
so, it is mostly a redundant club yardage - you could consider testing it with sponsor apparel as a maxed out hybrid that plays closer to a 3wd yardage but to do that you have to ditch the SE hat and most people prefer lengthening the driver distance.
And - if you instead opt for maxed out iron distances - once again, your 3i will still play roughly the same as the hybrid... so why use a club with duplicated yardage?
it can be valuable in the lower to mid range club setups because it offers a longer fairway yardage but eventually - it can easily be phased out of play.
