Jeff,
It's personal preference, I have shot mechanicals since the mid 90's but the guy's that took me in and got me started all shot that particular head and that's all I've known. I have never had any issue's with that head therefore I have never had to think of switching.
They do pull out of a target fine, I use someold one's that have already earned their keep to practice with and keep the new ones for hunting.
One thing I would strongly suggest is check your KE and make sure you have good KE for an expandable, if you have good KE and your bow is tuned you should have no major differences between fixed and mechanical (depending on the head you use). Not all Broad Heads are created equal (fixed or mechanical)
