Pros: increased speed of contraction and increased strength. Good for throws, deadpoints, ice climbing, bouldering, bar brawls.
Cons: Increased girth and weight of muscles. Marginally affects endurance. Increased risk of injury.
One thing to consider is what boots you'll be putting them on. Some crampons fit on certain boots better than others.
Sabretooths are great crampons. Take a look at the Charlet Moser Black Ice, too.
If you have software that can resize the image (Photoshop) and retain the quality of the picture, that would work. Lower level image editing software will make it look crappy if you do it this way. If you don't have that - yeah...you have to scan it in at a higher dpi to get a bigger picture.
Computer monitors (digital projectors) max out at around 100 dpi, so scanning at a resolution higher than this is overkill. Pay attention to your image size (dimensions) because that's what will keep your images from getting "blocky".
It was around this time last year when I sat next to my friend in the hospital. He was in a coma for about a week with seven skull fractures, and he turned out okay. Hang in there 'bone. My thoughts are with you guys.
