Dungarvan South West Ridge Scrambling

I'm trying to play with some alternative ways of labeling scrambling route images. The following image seems to work well on a computer, but seems to struggle on an iPod. I've tried rotating the image to allow the magnification limits to work better.  Still seems like the text needs to be a big bigger.  Too much more though and I worry about it being too cartoony...

The updated app image - thanks Mark
