I use a combination of hicaps and midcaps. I find its nice to run primarily midcaps and have a couple hicaps to fall back on (though Im never usually that trigger happy)
Then again, sometimes it jsut nice to be able to use a hicap and not have to worry about it for a while.
The Silver Dragon is to the 1911 as the GSX-R1000 is to the Grand Vitara. They'll both get you down the road, but one helps you compensate for your shortcomings. "sleepy"
Whatever I happen to have. I must say I prefer mids, just because I hate winding, and I hate having only 30 rounds. But I have seven reals for competition.
For me, it depends on what I'm carrying. My G36 is a support weapon, so it's hi-caps and box mag. I carry a few mids and three high-caps for my Aug on any given day, as well as my type 97. For CQB... They don't make MP40 high-caps.
For my AUG I have High caps, cheap 60rnd standards, and a few Mid caps. For my MP5 I have STAR standards four mid caps and three hicaps. My M16 has one hicap and 10 STAR real caps. I use a combination of all three types depending on what I want to use my replica for.
