I would reccomend the monotechs, they are very tough heads. Some production runs were known for not being scaple sharp but the newer ones are very sharp. I like the fact that they are easily re-sharpened when needed. Gosh, to hear some folks it's like the end of the world! [8D]
They also make a teflon coated practice heads in all weights.

To all those here that tried the G5's and dont like them you can send them to me as I have plenty of room in my archery box for them. 85,100 or 125 grains it doesnt matter. Heck, I'll even pay the shipping.
