RE: expandable broadheads
I use NAP 100grain spitfires. They fly just like my field points. Like was mentioned earlier, dont worry about them being closed after a pass through, the skin snaps them back sometimes.
Why am I sittin here on this stupid PC when I could be huntin'

What poundage would you recommend being able to shoot at before using expandable broadheads?
I just updated my website. Go check it out. I have big bucks, paintings, my drawings and more. Sign the guestbook while there.

All I got was "site under construction."
This next is controversial. I believe that the potential energy (PE) that your bow stores gives you a budget. You then decide how to spend that budget. You can spend it on speed (lighter arrows) or on penetration (heavier arrows). With current compounds and heavy bows and hard cams you can have both - good penetration and a fast arrow as you start out as such a rich archer - rich in PE.
Most mechanicals also use up some of the penetration. They may not be cut to the tip. They might have a large cutting diameter. They may be of a design that spends some penetration to open.
With the above high PE bow, you still have enough budget to shoot a good mechanical.
One last complication is that it is the penetration capability at impact that is important - how much PE was coupled to the KE of the arrow, how much drag was on the arrow and how much that drag slowed the arrow down.
So I would agree with 5 point that the bow poundage is not enough information.
If you are shooting a relatively light bow, though, you could still shoot mechanicals by choosing one with a above average penetrating design - 5 shot likes the Rocky Mountain Snyper - and/or you could shoot a relatively heavy arrow. The relatively heavy arrow will have a little more KE off of the bow due to the better coupling of the bows PE to the arrows KE, it will have more momentum - more mass to go with the lesser velocity - and hence more penetration potential than a lighter arrow. And it will likely shed energy less rapidly in the air (just like the greater momentum helps the arrow penetrate a deer, it also helps it penetrate the air).
