Nothing wrong with trying something different (although if you sub out the pheasant then is it really a Pheasant Tail any more?).
Howard Cole's LOF Pheasant Tail
Hot Wire Tarcher Pheasant Tail
Flashback PT Softhackle (used ostrich for the hackle)
Here's some I tied with hen pheasant tail
basic

beadhead
beadhead full flashback
Soft Hackle (split thread)
Charlie Craven's Pheasant Tail Alternative is a cool looking fly and doesn't use any at all
