It depends on the bait, how big the tail is relevant to the bait, type of tail ( hard to soft )...
Generally for argument sake glide baits have a stationary tail and wake/divers have a moveable tail.
Yes the type of tail can/will drastically give or take away movement depending on the bait.
Specifics can only be answered properly with the type, size and weight of the bait.
Built a few baits.... I always try several different tails to get the exact action I want.
