Ice climbing is like having fun but different. You are usually cold, miserable, wet and climbing on a dangerously inconsistent medium with typically unreliable protection, whats not to like.
Belaying the leader is even worse. Trying to fight off hypothermia and avoid falling ice while paying attention to the leader who is taking a worse line and going a lot slower than you would if it was your turn is a blast. No laying on a rock basking in the sun with your shoes off watching scantly clad tan beauties cruise up a pitch. Like I said whats not to like.
The physical act of ice climbing is different from rock too in that on rock climbs you MUST adapt your body to the rock but on an ice climb, with a little bit of bashing you can adapt the ice to your body position or type. Being short I know this well. On long routes efficiency is everything and simply bashing your way up won't get you far. Smooth swings and placements of picks and crampon points that use natural features or holes from previous placements are a must.
As far as protection goes, ice screws are not inherently inferior to any form of rock pro. The difference is in the the medium into which they are placed. Thick, defect free ice is very strong stuff. A well placed screw, with a slight down angle and flush to the surface, will hold even a long leader fall. The problem is most ice isn't thick and defect free.
Placing ice protection takes time and is much more strenuous than on a typical rock route. Frequently screws are misplaced or tied off short. Tying off screws is dangerous. Although, clipping bolts or plug and chug cam placements are not usually options on ice climbs. Its better to run things out a bit and take advantage of good stances to make placements than put in a bunch of poor protection. Using shock load reducing slings and equalized anchors are good ideas as well. A cheater sling to hang off tools is sometimes helpful and on long steep routes in cold weather might be the only way to get pro placed.
I grew up in Alaska and have lead, followed, soloed and free soloed hundreds of pitches of everything from easy alpine ice to WI 6. Dress warm, wear a helmet and face protection, climb with competent partners, practice placing lots of pro and have fun. A thermos of hot tea will be your best friend.
