I take the opposite view from Matt, I like a long tail and don't have any issues with short strikes unless I am fishing bluegills! Even my little 1/32 Oz Roadrunners end up being 2 3/4" to 3" long with marabou tail. I have had some tell me that for as many years as I have tied jigs, something over 12 years and most stopped telling me that a long time ago. I never have had any complaints from anyone I have tied a jig for. I even fish with braid and just don't have any issues with tail length! Most of my tails extend about 1 1/2" passed the end of the hook. However that is just me and my opinion and I do know there are plenty of guys that like a short tail. So I say tie your jigs the way you like them!
Really I do not think it matters all that much especially with a Hackle tail, but my Marabou with a little length and it looks like it's swimming!
